Comment 44 for bug 220628

I see this bug (or something that looks like it!) every few days using the Ubuntu 8.10 shipped Firefox 3.0.5 ("3.0.5+nobinonly-0ubuntu0.8.10.1", ATM), on a 2-core x86-64 (xlib 1.1.5, xcb 1.1.noidea). The last crash I captured was from CreatePixmap (request code 53), not sure if I'm seeing it on other requests or not. I've never seen it with any application besides firefox. (Though firefox is presumably pushing the X library stack a lot harder than anything else I use; I don't run multi-day OOo sessions.)

Restarting firefox is about the most frustrating computing experience I can think of (cf #177175), so I'm certainly eager to help...

...however, I suspect this was tracked down already in March (though ignored until November):
