Thanks, so yes, that sounds like a plain bug in libX11.

Now I'm not sure if I prefer the crash or the hideous workaround.
At the very least, the hideous workaround should be wrapped in
"#ifdef HIDEOUS_WORKAROUND" (or some more descriptive name).  Ideally,
we could then use an autoconf macro to only activate the workaround when
needed.
