Public bug reported:
I keep my PC up-2-date with Oneric. Within the last week, an update
caused both Xephyr and Xnest to no longer work. Most likely an Xserver
update or Glibc update. I run with the following command:
Xephyr :1 -query 192.168.15.70 -screen 1400x1050
And see the window pop up briefly then the crash. I am attempting to
connect to a Virtual Machine (kvm) that has XDMCP running in an
up-2-date install of Precise Pangolin. Running using Xnest instead of
Xephyr results in the same.
