Hi Brian,
please read this message:
http://lists.debian.org/debian-devel-announce/2006/11/msg00010.html

This message represents a bug in a caller of libX11, so if you can
reproduce this assertion, please try to get a backtrace with gdb and see
which library/application is calling XLockDisplay()/XUnlockDisplay(),
this will tell you where the bug is.

Thanks,
Julien
