Description Constantin Berzan 2009-06-14 19:08:41 UTC 
Application that crashed: gwenview
Version of the application: 2.3.0
KDE Version: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2))
Qt Version: 4.5.0
Operating System: Linux 2.6.28-11-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
100% reproducible here with KDE4.3beta2 from Ubuntu packages, Gwenview 2.3.0, qt "4.5.0-0ubuntu4.1":
1) Create a new directory and in it put an image, a video, and another image (so that gwenview traverses them in that order, for example a.jpg, b.avi, c.jpg).
2) Launch gwenview on the first image.
3) Press space to advance to the movie.
4) Quickly press space again to advance to the last image. -> crash.

It doesn't seem to crash if I wait long enough (~3sec) while the movie is playing, before advancing to the next image.

I am willing to do more testing if it helps solve this bug.  Thanks for the amazing work on Gwenview for KDE4!

Comment 1 mahen 2009-08-09 12:33:19 UTC 
I think I encountered the same issue.
KDE : 4.3.0, Kubuntu backports packages.

I have some .mov files among some of my pictures directories.
When stumbling upon a movie, and skipping it (that is to say, loading the next/previous picture/movie), Gwenview instantly crashes.
Comment 2 mahen 2009-08-09 13:38:27 UTC 
Note : I wish I could provide you with a debug log, but there is apparently no gwenview-dbg package in the Kubuntu backports repository. I installed various other KDE related -dbg but it doesn't add any piece of information.

Also, the crash occurs if the movie (.avi actually) is skipped very quickly.
Comment 3 Aurelien Gateau 2009-08-10 10:06:58 UTC 
I can reproduce this bug and added it to my TODO list. Thanks for the report.

Comment 14 Daniel Mader 2009-11-06 11:50:35 UTC 
Hi, this seems to be a very prominent bug, considering all the dups of it.

As a temporal workaround, until the movie playback feature works stable (here it also crashes even when I don't switch rapidly to the next image/movie), I'd suggest to make it configurable which file types should be displayed by gwenview. With this, as a default, I'd disable movie playback for now. It makes this otherwise great application look very flaky.

Thanks very much in advance for considering it!
Comment 15 Marcelo Sales 2009-11-06 19:31:44 UTC 
I agree with comment #14. Displaying several kinds of media files in Gwenview is nice, but many unforseen problems can arise because of that. These problems can be avoided if the user has the option to select which file types should be displayed.
Even if there were no problems, such an option would still be useful.

i'm also plaqued by this bug. gwenview doesn't even play the movies but still crashes. what helps as a workaround is to wait for 3 seconds before leaving the movie.

Comment 34 Aurelien Gateau 2009-12-19 18:44:54 UTC 
I can't reproduce the bug anymore with Qt 4.6 and Phonon 4.3.80. I suspect this was either Qt or Phonon related.
Comment 35 Aurelien Gateau 2009-12-19 18:45:48 UTC 
Closing the bug, please reopen if you can still reproduce it with Qt 4.6 and Phonon 4.3.80.

Comment 44 Dario Andres 2010-01-08 13:08:29 UTC 
@Murz: if you can repeat your crash, please, install the "kdegraphics-dbg" and "libqt4-dbg" packages and use the Crash Handler dialog to report the bug. That will create a new report which we will evaluate, to check if this is the same issue or a different one. Thanks
