xcb_io.c:285: _XAllocID: Assertion `!(dpy->flags & (1L << 3))' failed.

   On Fedora 8, the new X11 is breaking programs like nmrDraw from NMRPipe.
The program runs fine under Fedora 7 but fails under Fedora 8 with the error...

nmrdraw: xcb_io.c:285: _XAllocID: Assertion `!(dpy->flags & (1L << 3))' failed.
Abort

This problem also has been reported for the latest OpenSuse. I found the following
thread which sounds like the problem...

Unfortunately, it seems that we may need to rebuild X11 to disable some of these
new tests.
