This happened in oneiric, August 13th 2011.

[Martin Wildam (mwildam)]

In my case happened (after all updates for Oneiric beta 2) during report of crash in bug #857769.

[Martin Wildam (mwildam)]

After the crash unity, top panel and all window decorations were gone and I was not able to type anything. But I am not sure if that effect was due to this crash or due to the other (from bug #857769) because they happened together.

[Frédéric Hoogstoel (frederic-hoogstoel)]

I get this crash message when I open a standard unity session since I upgraded fron Ubuntu 11.10 to 12.04. I get no top panel, no application launcher.
The crash message indicates that this is a duplicate of bug : https://bugs.launchpad.net/bugs/976513, but this bug page does not exist.
I have to use Unity 2D.
My computer is a laptop DELL Latitude E4300.

As part of the big bug clear up for 16.04 LTS I am marking this bug as Wont Fix.
These types of crasher are better handled by errors.ubutnu.com which can collate similar crash reports to help us identify persitent bugs rather than one-off crashes.
Sorry we are not able to help with this specific issue. If you are still experiencing this crash, please re-open the bug and add the tag "desktop-bugscrub-reopened". See https://wiki.ubuntu.com/BigDesktopBugScrub for more information.
