I was having similar problems using the Xephyr version in unstable and
testing. Doing a downgrade to the Stable version, it works perfectly,
well it doesn't crash.
Now I don't remember the exact version numbers.

This is a temporary solution, since it should be able to use the new
Xephyr version perfectly.

Best Regards.
