Comment 34 for bug 1745345

It is not appropriate to have a gstreamer-vaapi task here because there's nothing you can do in that package that is an acceptable fix for Xorg crashing. It's not a fix, it is a workaround.

If you remove "gstreamer1.0-vaapi", then that might be a good workaround for some people. But no possible change to that package is an acceptable fix to stop any other package from crashing Xorg in similar ways in future.
