compiz.real crashed with SIGSEGV in thumbPaintThumb()

[Pauli Virtanen]

Binary package hint: compiz

Compiz crashed when (I think) I moved the cursor on top of the window list in the panel. IIRC, instead of a thumbnail preview, a small "thumbnail" containing garbage appeared, instead of a thumbnail of the Firefox window.

The Xorg video drivers are the binary drivers from Nvidia. This is on current Jaunty.

(Metacity replaced compiz OK after the crash, and apport was triggered.)

Some more information: this is not easily reproduceable, and I'm not sure how to trigger this. However, I've seen Compiz crash recently, possibly in a similar way, so it may be that this is not a once-off crash.
