Comment 11 for bug 799255

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.

BTW the bug on Oneiric is 834422 ; this is for tracking only the Natty problem. Thanks all.
