Hi

I did some more testing. I ran the xscreensaver package from Hoary on my
Edgy system with no crash. Hoary shipped xscreensaver v4.16. Breezy (the
version where crashes started happening) ships xscreensaver v4.21. If
you look at the xscreensaver changelog entry for v4.20
http://www.jwz.org/xscreensaver/changelog.html you will see:

* starwars uses texture-mapped fonts now.

It seems likely that this is what is causing the problem. What is strange is 
that no other GL screensavers cause a crash though.
I would like to try and run a v4.20 or newer xscreensaver on a Hoary system to 
see if the xscreensaver update merely exposed a latent Xorg bug or if the Xorg 
crashing is also a newer bug.

BTW, I see this bug is marked as need info. Is there any more info I can
provide? I'm willing to run debug-testing code or whatever it takes on
my machine to get to the bottom of this.
