Probably duplicate of Bug 41073. Do you have installed the extension ""Default Settings For Japanese"?

No, do not have that extension installed. 

This is new behavior, just having started, with no accompanying update or extension installation.

I have experienced this bug as well. Happens when I drag a workbook tab from one place to another. Crashes when you release the tab in the new location. Note this happens on every spreadsheet I have tried, including a new one. I have no fancy add-ons.

Can you give some more details, please. I can't reproduce it here. Neither with my 3-4, 3-5 nor my master build.

Did you edit a cell while moving sheets?

And do you use Ubuntu?

Created attachment 54263 [details]
Screenshot of Spreadsheet workbook details (properties)

Only way to show document properties without sending workbook. Workbook is proprietary & confidential.

Sorry it took so long...

KDE 8.0
LibreOffice 3.4.4 
OOO340m1 (Build:402)
Name     Firefox
Version  8.0
User Agent Mozilla/5.0 (Ubuntu; X11; Linux i686; rv:8.0) Gecko/20100101 Firefox/8.0

Just tried it again. Workbook has ~ 32 tabs, moved one, took down both Spreadsheet & Writer. [Document details in attached screenshot]

This is different workbook than last test.

I suspect either a bug in the KDE integration or in one of ubuntu/debian patches?

Could you try to get a stack trace with debugging symbols?

As this is not ever caught by the crash handler, I'm going to need help in capturing the info you need.

I have no problem in providing the supporting information needed, I just need to be cognizant of the confidentiality of the document(s) in question.

Here is a short log how to do that: http://wiki.documentfoundation.org/BugReport#How_to_get_backtrace_.28on_Linux.29

The corresponding Ubuntu package should be libreoffice-dbg

Have installed libreoffice-dbg debug package 1:3.4.4-0ubuntu1

Crashes *are not* caught, no debug information is created. Ever. No matter what Libre app crashes, nothing is ever caught.

Yes, this problem is still reproducable.

I can reproduce this easily in LibreOffice Calc. I just open a fresh new document and try to move any tab anywhere. Immediate crash.

LibreOffice 3.4.4 
OOO340m1 (Build:402)

Ubuntu 11.10 + KDE 4.7.4

Reinstalled LibreOffice with NO KDE integration package (libreoffice-kde) and the issue is gone (along with another one where the caption on mouse-over wouldn't show; only a black rectangle)

KDE related.

Lubos?

In evaluating the comment from Gaba [2011-12-20] performed the following:

1. Completely removed LibreOffice-kde
2. Did *NOT* remove or reinstall LibreOffice
3. Rebooted
4. Tested with 3.4.4 of LibreOffice

Problem is resolved. No further crashes. No further annoying little black boxes instead of tool-tips.

Problem is almost certainly with LibreOffice-kde

Closed as far as I'm concerned.

Thanks, Gaba!
