Thank you for your report!

However, processing it in order to get sufficient information for the
developers failed (it does not generate a useful symbolic stack trace). This
might be caused by some outdated packages which were installed on your system
at the time of the report:

no debug symbol package found for libevdev2
outdated debug symbol package for libgudev-1.0-0: package version 1:208-8ubuntu2 dbgsym version 208-8ubuntu2
no debug symbol package found for libxshmfence1

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!
