Moving back to xorg-server, tagging with xmir. It's a crash in the archive, and I'm not sure if the apport retracer will retrace bugs targeted at the XMir pseudo-project.

Need to check that we can forgo declaring some of those and that XMir wraps the ones it requires for itself.

Enter/LeaveVT must be defined.

Upstream and branches fixed.

This should have been fixed in the last couple of xserver-xorg-video-intel uploads. I'm not sure why the bug closing magic hasn't kicked in.
