compiz crashed with SIGSEGV in CompOption::Value::operator==()

[Erik B. Andersen]

Binary package hint: compiz

All I did was logged into the single user I have on my machine. I could see the background, but nothing else came up. I pressed Ctrl Alt Del to get the restart dialog, and about then I got apport telling me compiz crashed. (I never did get the restart dialog, until I eventually pressed Ctrl Alt Del again.) None of the windows apport opened had borders.

I have an Nvidia card and I am running the Experimental 3d drivers as installable by jockey. (I did have compiz and those drivers working just fine. This is the first time I've had compiz crash.)

I will see if logging in again triggers this bug. I will also try restarting and then logging in.
(Edit:neither re-triggered the bug.)
