Description Patrick Carabin 2019-06-05 19:20:42 UTC 
Application: kdeinit5 (5.0.97)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-51-generic i686
Distribution: Ubuntu 18.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed:
just logging in. It happens at each login.
- Unusual behavior I noticed:
It seems the tabs in konqueror are duplicated after each crash.

The crash can be reproduced every time.

-- Backtrace:
Application: Konqueror (kdeinit5), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
