Comment 2 for bug 778470

Still the case on an up-to-date Oneiric. If needed, crash file is still in /var/crash which I was about to upload via apport, but found this bug and only confirmed.
Reproducable.
Disable automatic plugin sorting in CCSM. Enable cube, rotate and switcher, disable wall and staticswitcher. Enable automatic plugin sorting. Panel disrupts, desktop gets emptied. No keystrokes work, hardreset, recovery mode root shell gives the topic message when trying to reset Unity. Didn't let me mount encrypted /home either in order to remove files.
Never got back a working desktop and wanted to reinstall with usb-stick, which didn't boot, but was displayed on the empty desktop. Double click on usb-stick opened Nautilus, removed recently changed session files and compizconf, which resulted in bringing back launcher and panel. Conclusion for now, rather leave CCSM alone.
