Description Jean-Baptiste Faure 2013-10-13 16:36:30 UTC
Step to reproduce:
- launch the master, open the StartCenter
- in the collection of recently used files, open one which is shown by its thumbnail (preview)
- do a change on this file and undo it so that the status of this file becomes "modified"
- save the file and close it ; return to the StartCenter
- the preview of this file is now a small square instead of a preview of its first page
- close LO
- go to the directory containing the modified file
- change the extension of the filename to .zip
- extract this archive
- open the directory produced by the archive extraction
- go to Thumbnails directory ==> the file thumbnail.png is very small (~4 ko).

- open the file with LO 4.1
- make a change and save the file
- look at the thumbnail : it is back.

Best regards. JBF

JBF, can you please tell us the commit id of the version where you see
this problem.

FWIW, I do not see the problem with either commit 95e95e0 (fetched
2013-09-19) or the latest version in the daily (2013-10-04).  With
each of these, my thumbnails/thumbnail.png grew from 4240B tp 5581B;
an image comparison program sees lots of pixels different, but the
difference is too subtle for my eyes to see.

Oups, sorry, forgot to add that:Build ID: d7961b15572373a29cc0839858ae514db6238ccd
Tested on Ubuntu 13.04 x86-64

Confirmed on Ubuntu with version 12b1ca3236aa167c007c6c87e0d2f2d06c495821.

It creates a thumbnails, but 3 by 4 px.
Comment 4 V Stuart Foote 2014-01-04 21:06:02 UTC
@JBF, still a valid issue?
Comment 5 Jean-Baptiste Faure 2014-01-05 09:10:56 UTC
Works as expected on version (Build ID: 227fb8c9c3b22798b90aff9b17605428b7f9a897)
and on the master Version: (Build ID: c2b40175fd2b6ec2169e89ffd3bac14a3cf679dc)

I do not know which commit fixed the bug, so closing as WorksForMe.

Best regards. JBF
