Does it still happen with 1.6.0-1 and can you provide a .PPS to
reproduce the problem?

Alternatively, can you get a backtrace of all threads (after installing
the relevant debug packages) of the crash?

I also see that you're using ffmpeg from Debian Multimedia. That will
easily cause crashes in gst-libav! Please use the ones from Debian.
