GTK build crashes under X

[Stephen Berman]

I've been using the GTK build of the first pretest tarball for almost
three weeks without any serious problems.  But as of today it
immediately segfaults when I start it under X.  The only change to my
system (SUSE 10.1) between today and the last time I started this
build of Emacs is that I installed the following software packages:

qamix-0.0.7e-165              
audacity-1.3.2-0.pm.beta      
wxGTK-2.6.2.1-20              
kstreamripper-0.3.4-1.pm.1    
streamripper-1.61.18-1        
apache2-doc-2.2.0-21          
streamtuner-0.99.99-23        
libmspack-0.0.20040308alpha-16

Could wxGTK be the culprit?  (There's no problem when I start this
Emacs with -nw, nor with a Lucid build of the same pretest tarbell
under X.)  Below are the gdb and lisp backtraces.  Please let me know
if I should provide more information.
