Comment 1 Christoph Feck 2014-05-19 20:24:15 UTC 
Does digikam use X11 calls from multiple threads? If yes, probably lacks XInitThreads(); somewhere.
Comment 2 Christoph Feck 2014-05-19 20:25:42 UTC 
Ah well, it is "libgstxvimagesink.so" which uses X11. Not sure if the bug is in phonon-gstreamer of gstreamer itself.
Comment 3 foren 2014-05-20 05:53:03 UTC 
Playing around a little (on an onther machine), it seems that I have the problem not only by the mp4 file or thumbnail generation .... But I can not provide a stacktrace for that at the moment (sorry for that) ... 

Perhaps it has something there is a intereference because of my configuration? I'm using on both maschines ubuntu 14.04 (unity) with PPA: https://launchpad.net/~msylwester/+archive/digikam (like suggested by Michal here: http://www.digikam.org/node/713#comments)
Comment 4 Myriam Schweingruber 2014-08-10 13:10:43 UTC 
Is this still reproducible? Then please install debugging symbols for phonon and phonon-backend-gstreamer and provide a new backtrace.
Comment 5 caulier.gilles 2017-01-06 22:11:13 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...
