See i.e. http://code.google.com/p/clementine-player/issues/detail?id=450 Breaks .m4a playback that was encoded with iTunes. libgstqtdemux.so isn't in /usr/lib64/gstreamer-0.10/ despite gst-plugins-meta installed. Reproducible: Always
Rebuilding gst-plugins-bad fixed the issue. Not sure there's a bug here, unless there was some change without a revbump.
Feel free to reopen.
