Description Tommy Lehmann 2017-05-06 08:11:13 UTC 
Application: kontact (5.4.3)

Qt Version: 5.7.1
Frameworks Version: 5.33.0
Operating System: Linux 4.10.13-200.fc25.x86_64 x86_64
Distribution: "Fedora release 25 (Twenty Five)"

-- Information about the crash:
- What I was doing when the application crashed:
 I just tried to start the application. If it happens once it usualy happens multiple times up to "it seams like forever". After a while 5 starts or even a few weeks with 100reds of tries it usually continues working without any noticable change.

The crash can be reproduced every time.

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