Sentry Crash Report:

Description rainer 2016-08-25 17:09:14 UTC 
Application: kontact (5.2.3)

Qt Version: 5.6.1
Frameworks Version: 5.24.0
Operating System: Linux 4.7.1-1-default x86_64
Distribution: "openSUSE Tumbleweed (20160822) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Currently I have seemingly some issues with kontact/akonadi. Here I deleted the last serach folder which led to a weird UI of kmail (folder tree with empty labels). I wnated to restart, therefore closed it, which led to this crash.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
