Thank you taking the time to report this bug and helping to make Ubuntu better. However, processing the crash report to get detailed information for the developers failed as the retracer did not generate a useful symbolic stack trace.
Please try to obtain a backtrace manually following the instructions at http://wiki.ubuntu.com/DebuggingProgramCrash and upload the backtrace (as an attachment) to the bug report. This will greatly help us in tracking down your problem.

Switch to "confirmed" as a stack trace was joined, and the bug is reproductible (got it too)

Seems complete for me, as it has a duplicate which was assigned to
ubuntu-desktop bugs, it seems for me for both reasons a good idea to
assign it to them.
