Comment 12 for bug 450021

I ran into this bug on Gentoo. The patch 2 in https://bugzilla.mozilla.org/show_bug.cgi?id=631518 seems to have fixed this. That patch was also used to fix https://bugs.launchpad.net/compiz/+bug/438868 so looks like this bug should be fixed in Ubuntu (at least Lucid and Maverick).

Also, I found a way to consistently reproduce this bug: lock the screen, bring up the password dialog by pressing a key or moving the mouse, wait until it times out and disappears, then bring it up again and enter your password. At least for me this triggered the bug every time with unpatched compiz.
