The crucial patch I found that was needed for BLT 3.0 (CVS) is here:

http://lists.gnu.org/archive/html/swarm-hackers/2008-08/msg00000.html

The `deep' change (as opposed to the crud that needed to get a compile), 
is the addition of the inputStyle slot for Tk 8.5.  I see the patches 
for BLT 2.4 for Fedora 9 distributed in the SRPM has that, but it also 
has a whole bunch of other changes too.  Certainly a bug in the X11 
stuff in BLT could (and probably is) creating the problem you see.   I 
was having actually crashes not X complaints but that was on x86_64.

Sounds like you aren't getting a useful debug trace because X11 is not 
in sync with the program.   If you find the call to XSynchronize and 
move it outside the following #endif, you can force it to be in sync.
