[Jason S. Wagner]

Occurred when removing "Help" icon from the Favorites bar.

Ubuntu Software Center was stuck installing Audacity in the background, and after the crash it finally moved onto the next task.

Status changed to 'Confirmed' because the bug affects multiple users.

[Tim Lunn (darkxst)]

This was fixed in mutter 3.4.0, so looks like this should only affect Oneiric, which is almost EOL anyway

[Tim Lunn (darkxst)]

Thank you for reporting this bug to Ubuntu. DISTRO reached EOL on DATE.
Please see this document for currently supported Ubuntu releases:

I've tried recreating this bug with DISTRO and was unable to, given the information you've provided. Please either a) upgrade and test or b) increase the verbosity of the steps to recreate it so we can try again.

Please feel free to report any other bugs you may find.
