[Xcb] Bug #9051

[Stephen Dawkins]

Hi

I am having a problem with bug 9051. Every time I start a GTK2 application
it dies with the following message:

gnome-terminal: xcb_lock.c:62: _XGetXCBBuffer: Assertion `((int)
((xcb_req) - (dpy->request)) >= 0)' failed.
gnome-terminal: xcb_xlib.c:41: xcb_xlib_lock: Assertion `!c->xlib.lock'
failed.
Multiple segmentation faults occurred; can't display error dialogue

The application worked fine before I upgraded X. The interesting thing I
found about this bug is that it only occurs when there is a window manager
running (I've tried twm and metacity), if I kill the WM and start the app
it runs fine. If I then start the WM, the app dies.

Does anyone have any idea what is causing this, or know of anything I can
do to get more useful debugging (I've already attached a backtrace to the
bug).

Thanks & Regards
Stephen
