Description Jean-Baptiste Faure 2013-08-08 15:49:20 UTC 
The following file https://projects.kde.org/attachments/2/20110319-KDE4.6_release_party-skrooge.odp crahses LibreOffice 4.1.x and the master when starting the slideshow (F5).
Tested on Ubuntu 12.04 x86-64 with LO 4.1.0.4 (stable release from TDF), 4.1.2.0.0+ (Build ID: 88fec7695f5f3c9574bc305e31120758004493c) and the master (Build ID: d65c44020bf32713af4985f598f7b532a969247a).
It seems that the problem comes from the fade smoothly transition. If I remove this transition there is no crash in slide show mode. If I try to add the same transition I get a crash or a freeze.

Best regards. JBF

The crash is caused by commit a775188f6bbf3bbf8448b2b7398a1902908bb5e2. And there are some warnings from valgrind even after reverting that.

Comment 6 Jean-Baptiste Faure 2013-08-13 17:25:58 UTC 
Verified on Version: 4.1.2.0.0+ (Build ID: 63162c960ae6f0d70740a6bba2cf225d2d8d368).
Tests done:
- test file in slideshow mode: OK
- adding a fade smoothing transition on a slideshow without transition: OK
So works as expected. Thank you very much for the fix.

Best regards. JBF
