compiz crashed with SIGABRT in raise()

[Carla Sella]

While testing iso image http://cdimage.ubuntu.com/daily-live/20110803/oneiric-desktop-amd64.iso on live non persistent USB key, after about a minute having logged on compiz crashed.
I rebooted and it happened again.
I have two screen shots of the two crashes, I'm attaching them.

This does not happen with USB persistent key.
Seems to happen only with non pesistent USB key.
