GTK+ releases the lock during gtk_main(). In fact, the
gdk_threads_enter/leave pair here is required.
The cause of the errors is definitely that some GDK or X function is
being called outside of a gdk_thread_enter/leave pair.
(If you add just an enter and not a leave, then yes, your program
will hang next time the drawing code is hit.)
