Manuel (and other folks CC'ed),

Based on your screenshot and the fact that you're running Xephyr inside KVM, I
suspect that you're running into the (still open!) Xephyr-in-KVM-segfault bug:

   https://bugs.freedesktop.org/show_bug.cgi?id=32765

in its Fedora form:

   https://bugzilla.redhat.com/show_bug.cgi?id=518960

If I'm right, then you can probably fix the segfault you're seeing with a patch
similar to the one attached to the second ticket.

As for getting this fixed upstream:

   @Matthew: according to bugs.fd.o, #32765 is assigned to you. Are you in fact
     the right owner for this ticket?

   @Keith: in http://patchwork.freedesktop.org/patch/1327/, you asked Ajax for a
     tweak to his patch. Could you please spell out a little bit more explicitly
     what changes are needed, e.g., for those of us who are not yet expert X
     hackers but who might nevertheless be able to rebase, tweak, and test the
     patch...?

   @others -- I've added you to the CC list since you've all been previously
     involved in conversations about this bug...

Regards,

Michael
