Minimizing Firefox may crash X-server

[Bensin]

Description:
Minimizing Firefox 3.0b5 may crash X-server if the Visual Effects settings in Gnome (Under System -> Preferences ->Appearence -> Visual Effects) are set to "Normal". Also, I use the nVidia-driver.

The following may reproduce what I believe is the same bug:
Start a new session of Firefox and open youtube.com. Open a new tab and choose that tab. Start clicking on the Firefox-tab in the Gnome Panel/taskbar so that Firefox minimizes and restores itself. Click quite fast (approx 2-4 clicks per second) and sometimes up to 50 or more clicks in total. Eventually the X-server will crash and the login-screen appears.

The following is from /var/log/syslog at the time of the crasches:
"

"

I have been unable to reproduce this bug without opening the second tab in Firefox or if the Visual effects are set to "None".

Other than this bug, the system is stable. Viewing flash-content in Firefox works fine.

Pleaes try to disable your extensions in Tools -> Addons.

if that doesn't help: what video card (model) do you have? what
driver are you using?

off the top of my head it is an ati radeon with like 128mb of memory,
I can't find the box and don't want to open up my PC, but I am pretty
sure it is an ati radeon 5220.

Same problem... crashes on minimize (I always use the button). Compiz used. It's not a Firefox extension thing. I don't use extensions. I'm not even sure it's a Firefox thing but it has only happened to me with Firefox.
