compiz crashed with SIGSEGV in PrivateWindow::processMap()

[Jörg Possin]

Binary package hint: compiz

After adding some mp3`s to Audacious from a nfs mount nothing happened, the songs do not appear at audacious. I could not move the mouse arrow or change to another workspace with key shortcuts. I go to a console (ctrl + alt + f2) and have a look: process apport runs with 99% CPU. I changed back to gnome and in this moment it crashes.
I am using Ubuntu 11.04
