Bug Description

Binary package hint: compiz

I wasn't doing anything special, I was just trying to maximise a terminal window with alt-f10 I think. Apologies if this is a dupe but it's very difficult, even for a GStreamer/libav hacker, to see if this issue is the same as other previously reported issues.
