This problem also shipped with openSUSE 10.3; however it is easily fixed by doing a YaST Online Update (the patch to xorg-x11-libxcb causes a warning to be displayed instead of terminating).
However, some applications still produce other errors related to xcb, which the xorg-x11-libxcb update (and those fedora packages AFAIK) do not resolve, such as: xcb_lock.c:77: _XGetXCBBuffer: Assertion `((int) ((xcb_req) - (dpy->request)) >= 0)' failed. These kinds of errors can be fixed by compiling a libX11 without xcb entirely, and getting the desired app to use that particular libX11.so by setting LD_PRELOAD appropriately.
