Do you know if there is already a Vaapi / Nouveau bug tracking this issue? It
would be nice to have a pointer to it to be able to track progress on this.
And if there is no such bug report it would be nice if you could create one.

I have removed the gstreamer1.0-vaapi packages from the cw-gtx560 machine. This
should be the only TestBot machine that's impacted. A quick test does show that
the crash no longer happens. This should show up on tomorrow's WineTest
results.

What are the impacts for Wine users? Is it correct to assume that the presence
of the gstreamer1.0-vaapi package(s) would have also broken video playback in
other applications like VLC or Firefox+YouTube; thus making it essentially
unusable anyway? Or does it mean they have to choose between a working Wine and
video acceleration in other applications?
