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.

In my case, easily reproducible: on a dual-monitor setup, all I have to do is run 'unity --reset &'. Crashes every time.

BTW, I ran --reset for bug 833130.

I have tried running unity --reset from a Terminal (byobu) and it crashes. This is done within a Gnome Classic session running Gnome 3.2, and just a single monitor setup.

unity --reset segfaults for me on 11.10.

The issue that I had was a compiz config file in the ~/.compiz-1 directory. Once I deleted that unity --reset was able to bring back unity 3d.

unity --reset segfaults for me on Ubuntu 12.04 LTS

Didier, could you look at trapping that error? The issue got reported a bit over 600 times on errors.ubuntu.com this month, which means quite some users see whoopsie due to it, not sure the bug is worth tracking and fixing since that's on the reset command but we should at least catch it I guess, what do you think?

This bug was fixed in the package unity - 6.0.0-0ubuntu1

[ Didier Roche ]
* debian/rules, debian/control, debian/unity-autopilot.install:
- install new unity-autopilot package, containing autopilot bindings and
test for Unity
- add some python build-dep for executing setup.py
- use dh_python2 and add some python:Depends dep for automatic python
version detection
* debian/control:
- remove gnome-desktop dependency: not needed upstream anymore
- unity Breaks older lenses due to path change
- remove libgdu in build-dep
* debian/libunity-core-6.0-5.install, debian/libunity-core-6.0-dev.install,
debian/control:
