Kernel bug reported when attempting to connect via Xvnc using a gdm greeter. 
This prevents Xvnc logins.

How reproducible:


Steps to Reproduce:
1. Using libvirt, install a F-7 qemu guest.
2. On the guest change the /usr/share/gdm/defaults.conf

I do not know if the following information is relevent:  My guest system is a
i686 install.  My host is on x86_64.  I installed the kqemu kernel module on the
host, so I can use acceleration, since my machine does not support kvm.
