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.
