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:
I was using the application as usual, and attempted to close/re-open Kmail when the crash occured. I was restarting Kmail because it wasn't downloading my mail. I seem to have this problem a lot.

The crash can be reproduced every time.

-- Backtrace:
Application: kontact (kontact), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
