New crash information added by DrKonqi

After upgrading to 10.04LTS Digikam i suddenly got the KDE invoronment with the netbook remix. Since I prefer KDE I started it and it seems to be working fine besides the anoying KNotify crashes (which I can live with for now) and DigiKam now crashing too with segmentation fault. I have no idea if both are related, however I can report that DigiKam starts just fine when running Gnome.
Comment 3 Marcel Wiesweg 2010-06-30 18:30:43 UTC 
luv4tn: Crash occurs in the alsa driver in the GStreamer backend of Phonon. Not related to digikam.

Thanks Marcel ... but since I understand s**t what the output of the crash handler says I related this to what the crash handler said ... "digikam crashed ... segmentation fault" and this is misleading at least abit.
Comment 5 Marcel Wiesweg 2010-06-30 20:19:12 UTC 
Sure, I did not want to criticize you posting the bug. Just to give you a hint where to look for the problem (multimedia stack, gstreamer, phonon). Knotify crashing may be related.

Didn't felt criticized at all ... :-)

It was the right hint. Switched to the xine backend and Digikam runs fine now and guess what - Knotify doesn't crash anymore either. Thanks a lot!
Comment 7 caulier.gilles 2016-12-24 10:06:23 UTC 
digiKam 5.4.0 bundles will use QtAV framework instead Qt5Multimedia to thumb
and play video/audio. The Slideshow tool will also support video as well.

QtAV use ffmpeg codecs. It's multi-platform and will always available in
OSX, Windows and Linux bundles that digiKam team provide.

For Linux packagers, you will need to turn on video support at compilation time
and solve QtAV dependencies...
