Gambit starting error on OpenSuSE 11

I've installed OpenSuSE 11 and reinstalled Gambit 2.2.30. I have encountered following error when I run Gambit.

gambit: xcb_lock.c:77: _XGetXCBBuffer: Assertion `((int) ((xcb_req) - (dpy->request)) >= 0)' failed.

I don't know what's the exact reason, but I found a workaround after digging the net.

opensuse:~> gambit -x11 &

Good luck.
