Attempting to run virt-manager on a remote machine through an SSH tunnel with X11 forwarding fails.
With --debug output shows:
[Fri, 16 Jan 2015 21:03:02 virt-manager 4327] DEBUG (console:1494) Starting connect process for proto=spice trans=None connh

[xcb] Extra reply data still left in queue
[xcb] This is most likely caused by a broken X extension library
[xcb] Aborting, sorry about that.
