Application: kontact (5.1.46 pre)
 (Compiled from sources)
Qt Version: 5.4.2
Operating System: Linux 4.4.1 x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
- What I was doing when the application crashed:

Kontact (Kmail view) don't want to show mails in folder (this is another bug), so I restarted akonadi by `akonadictl restart`. Then, kontact crashed. It happens just once. I wasn't abble to reproduce it.

Kdepim and akonadi is installed from source:
kdepim head 0dc391800b63ac56f027ec269625da9662545b14
akonadi head 0c1c6bd492000d713e14562a825958c42e4d7b84

The crash does not seem to be reproducible.

-- Backtrace:
