Thanks for tracking it down.

I'm not sure I understand all the details, but I really find the
workaround hideous (tho I do think you for coming up with it): what if
we undo your recent change that does XrmSetDatabase(dpyinfo->display,
NULL) and just free the xrm database (i.e. introducing a double-free
crash in older libX11)?  Would this also work around this problem?
