1) Hm...could you also run 'info threads' in GDB and, if there are more than one of them,
collect all backtraces?

2) According to http://cgit.freedesktop.org/xorg/lib/libX11, libX11-1.5.0 is 18 months old.
Could you try an upgrade? My system has 1.6.0.

Jan, is it possible that 3rd-party library does X protocol calls in separate thread?
(Note this is Lucid build, and so GTK should be out of suspicion).
