Application: kontact ()

Qt Version: 5.4.2
Operating System: Linux 4.2.0-16-generic x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
- What I was doing when the application crashed: After starting the PIM kontact crashes immediately with the notion: Failed SpecialCollectionsRequestJob::slotResult "Could not create collection outbox, resourceId: 8"
This happened since upgrade to Kubuntu 15.10

The crash can be reproduced every time.

-- Backtrace:
Application: kontact (kontact), signal: Segmentation fault
