Nathaniel and Barton found a theoretical situation that would cause this crash
(http://lists.freedesktop.org/archives/xcb/2009-January/004248.html) but it hasn't actually been proven that this situation is happening.
If this situation is happening, it can be detected by

* getting debuginfo packages for libxcb, and
* setting a conditional breakpoint on the line in xcb_generate_id after the
  call to xcb_xc_misc_get_xid_range_reply, with condition "range->count == 1".

(It is not necessary to run with --sync.)
If the breakpoint is hit, then the program will crash soon afterwards.
If the BadIDChoice results without hitting the breakpoint, then there is also another bug.
