Description Daniel 2016-05-02 19:47:11 UTC 
Application: korgac (5.1.3)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-22-generic x86_64
Distribution: Ubuntu 16.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was trying to change the session using KMenu - Leave - New Session, tried it three times, because...
- Unusual behavior I noticed:
...after hitting it the first time, Kubuntu crashes totally (no virtual tty, no reisub worked, had to hard reset).

The crash can be reproduced every time.

-- Backtrace:
Application: KOrganizer Reminder Daemon (korgac), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
