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might be caused by some outdated packages which were installed on your system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!

If you could build a patched kernel in a PPA, I'd be happy to test.

I've tested the patch and can confirm it appears to fix the issue. :-)
