I followed what the reporter of #831529 suggested: I first tried to "apt
install --reinstall gstreamer1.0-libav", which had no effect. I then
upgraded to the version from experimental, ran gst-launch again, then
downgraded to the version from unstable, which also seem to not crash
I'm not very familiar with the gstreamer/libav/libva stack and thus
would like some help to get to the bottom of this. Frankly, I still
don't understand why x264 and VA-API is even at play here, when it's
just a pipeline of parsing a wav into a fakesink.
Regardless, I'm keeping this as an ffmpeg bug though (and at grave), as
the crashes started with the recent ffmpeg upgrade and the backtraces
seem to suggest that the abort() is coming from ffmpeg.
