-- Information about the crash:
I had tried to remove a n instance of a Google calendar that seems to be a duplicate of another calendar.  the delete calendar option does not remove the calendar.  I then went to Akonadi configuration to investigate if the Google calendar was showing a a resource.  It was not.  I then switched to email and none of my email folders were listed.  However the calendar resources were listed.  And then Kontact gave this crash.

-- Backtrace:
