Hi, can you get a backtrace of the crash with the following packages installed?
libglib2.0-0-dbg libgstreamer1.0-0-dbg gstreamer1.0-plugins-base-dbg gstreamer1.0-plugins-good-dbg gstreamer1.0-plugins-bad-dbg gstreamer1.0 -plugins-ugly-dbg gstreamer1.0-libav-dbg Also please check if the problem still exists with the GStreamer packages from experimental. The backtrace you provided is not really that helpful, but it could be a problem that is fixed since a while already related to liba52 (and not libav). Thanks!
