Description Andy 2014-01-14 16:12:43 UTC
Problem description: 
In the preview of recent documents shown at the start (new in 4.2), if you have a calc file with a narrow column followed by a very wide one, the preview shows only the very narrow first, resulting is quite abnormal thin preview.
For example, imagine that the calc document has a wide B column full of data, but since it cannot be seen completely, you see only column A which is just 0,5 cm. wide. Of course this suggest that the data in column B could not be printed on an A4 page as they are formatted now, but this should not cause the bad preview here where it does not have anything to do with the printing of the file.

Steps to reproduce:
1. in a Calc Sheet, set column A to 0,58 cm, and column B to 24 cm.; put in any data in both columns.
2. save and close the file with this first sheet as specified
3. close all files so as to visualize the start screen
4. you will see the calc file previewed as a very thin vertical column with nothing at its side, while all other previews will show a rectangular full page

Current behavior:
In this case the preview is pretty useless, as the only column shown gives very little information about the content

Expected behavior:

Operating System: Windows 7
Version: rc

As requested by mail, I confirm that the behaviour described is still the same in 4.4.4
When Calc Files have a thin first column and a wide second column, the preview shows only the thin first column and nothing else, giving a deformed preview.
The correct behaviour would show, in a uniform way with other files, the first part of the file with the same width x height proportion of other previews, even if the second column will be shown only partially.

As requested, I confirm that the problem is still present in LO5.2.1. Nothing has changed
