Thanks -- I did just that (after a few trial and errors) and was able to get it to crash: Received signal SIGSEGV, Segmentation fault.

Start up the server as normal, attach gdb to the Xorg pid, then trigger the crash and type bt in gdb. I would guess there's bad things going on in XKB, but XkbStringText shouldn't be crashing. -- Dan </blockquote></div> -- Rediscover the Web <a href="http://www.mozilla.com/firefox/">http://www.mozilla.com/firefox/</a>
