Beware Ubuntu 8.10 "Cruft Remover"

Updated my Ubuntu to 8.10 this week and have been poking around the new features.

Yesterday I found "Cruft Remover" under the System > Administration menu.  I assumed it was something similar to CCleaner on Windows. CCleaner scans your system and finds UNused items which are safe to remove.   Unfortunately the Cruft Remover tool itself provides no information or help only a "Cleanup" button which I gleefully pressed.

Unfortunately it appears to have deleted several apps I use regularly. Oops.

• VirtualBox? Gone.
• Air/Twhirl? Gone.

Not sure what else is missing.  But they definately need to improve the usability of this tool.  So if you have upgraded - beware of Cruft Remover!
