The file which which causes the crash.

This bug was filed from the crash reporting server and is br-42e0542a-7a05-42c3-9f12-aef321750f23.
=========================================

I have a document, which was created with LibreOffice Calc 6.0.2.1 (x64) at Windows 10. It can be opened and the second table gets displayed. Then I do a simple click on a table cell (for example E120) and LibreOffice Calc crashes immediately, and the document recovery is displayed instead. So far, I can repeat this crash over and over again on my system, as long as I do not recover the document. I'll attach the example file to this report.

@Eike, I thought you might be interested in this one...

Taking.
Comment 5 Eike Rathke 2018-05-17 09:58:00 UTC
There's an odd constellation of view settings regarding split/frozen ranges that makes things point into a non-existing range. This can be fixed when reading the document.

@Manuel:
Do you by chance remember how you created the frozen row on sheet "new", was it a different one before, or columns and rows frozen and then removed, or which menu entry you used and where the cell cursor was positioned then? That would be very helpful to find the place where the bad setting originated from.

Comment 8 bugzilladocumentfoundation 2018-05-17 22:58:22 UTC
@Eike:
I don't know for sure how I did freeze the row, so the following is more a vague reconstruction of what I probably did. But nothing is for sure.

First, it is very likely that before I used that "freeze first row" I first had used the split window function by grabbing this split marker directly above the right scroll bar, and pulling it downwards. I always used this way when I was working with huge tables in previous LibreOffice versions. I believe that later, because of the way an other very famous spreadsheet program which I use at my workplace is doing it, I was than looking for the "freeze rows/columns" function. This document is actually the first time that I use "freeze rows" with LibreOffice. I don't know if I undid the split window before using the freeze, or not.

When writing this comment, I just had a look at the interface and I found only two ways to do freeze the row. I am quite sure I did not use the toolbar icon with the dropdown. Therefore, I am somewhat sure that I used (German interface): 
menu "Ansicht" -> submenu "Zellen fixieren" -> entry "erste Zeile fixieren"
In English it is probably called:
menu "View" -> submenu "freeze cells" -> entry "freeze first row"

Unfortunately I don't remember anymore, whether I deleted the fixed row. In general I am the kind of guy who very often adds/deletes/moves rows/columns and for example I am quite sure that I added the first column (or moved it to that place) at a later point in time and I added the second column even later. 

On the one hand it is absolutely possible, that I deleted the first row after using the freeze row function. It could be that this first row originally was either an empty row or that I had double column headers in the first and second row. By double column header I mean the first row was used for grouping a few columns (with groups like "Pearls" and "Jewels" ), and second row for describing the column data within each group (like "amount" and "got it"), and data was starting at the third row. I remember that at some point in time I realized that LibreOffice has a limitation of only being able to freeze one single row instead of several rows (unlike in some other very famous spreadsheet program). I believe this was the reason why I changed it to a one line header, using text wrap. It could even be that I had both one empty row or a few empty rows and then after this two rows for such a double header. 

But on the other hand I am really not sure if I did such a thing and it could also be, that I did never change the first row by removing or adding a row.

I absolutely have no idea where the cell cursor was positioned, but there is a good chance that I positioned it like you need to do it in that other very famous spreadsheet program, which would be in the first column, and one row below my own column headers, which is the first data cell.

Sorry, that I can't remember more clearly.



One thing I forgot to mention, but I don't know if it is related or a completely separate topic:
The document was created over days only by using LibreOffice. During the creation I was using a lot of ALT+TAB in Windows 10 for switching between a 3D game and LibreOffice. I often had the problem that at some point in time the keyboard binding in LibreOffice seemed to change. The normal arrow keys (up/down/left/right) did no longer move the cursor from cell to cell. Instead they where scrolling the document, in the same way as it does when you click on the arrow keys at the end of scroll bars. I looked up the key binding in the settings, but the up/down/left/right keys were defined as usual. I might have overlooked it, but in those settings I did not even found a command to scroll the document into a certain direction, which you would be able to assign to a key. And also there doesn't seem to be a combination with ALT/SHIFT/CTRL which does such a scrolling. 
I usually ignored the problem, and the next day (when Windows was shut down and restarted) it was OK. But it occurred very often within a few days before and after my discovery of the crash described in this bug report. I am still working with the repaired version of the document quite regularly, but then at some day this scrolling issue did never occur again.

Thanks for the explanation, alas, I couldn't reproduce the odd values yet.

Anyway, this

is not related, that is the behaviour if the ScrollLock key is activated
(same as in Excel).
