The crash happened under no special circumstance. All applications were closed (pure desktop). Last closed App was Firefox. With some delay, apport popped up and redirected to this page.

edit:
The machine is a HP EliteBook 2760p running wily which has been updated stepwise from 12.4LTS.

Nobody here to give me a hint how to correctly upload a .crash file?

Knowingly it's not pretty, because all data are cluttered together in the same file, here it is ...

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

This crash occurs when I click the calendar or the shutdown button on the top bar.
