 Thank you for taking the time to report this bug and helping to make Ubuntu better.

However, processing it in order to get sufficient information for the developers failed (it does not generate an useful symbolic stack trace). This might be caused by some outdated packages which were installed on your system at the time of the report. Please upgrade your system to the latest package versions. If you still encounter the crash, please file a new report.

Thank you for your understanding, and sorry for the inconvenience!
