Glade has a small FAQ at http://glade.pn.org

RH 7.0 has XFree86 4.0.1 which is known to be a bit buggy, so that may
be the problem.

But it is a bit unusual to call XInitThreads in a GTK+ program.
Do they really need to do that? GTK+ has its own exclusive lock that most
threaded apps use - i.e. GDK_THREADS_ENTER()/GDK_THREADS_LEAVE().
