Bug 381998

Application: korgac (5.2.3)

Qt Version: 5.7.1
Frameworks Version: 5.31.0
Operating System: Linux 4.10.0-26-generic x86_64
Distribution: Ubuntu 17.04

-- Information about the crash:
- What I was doing when the application crashed:
Nothing at all! I waited for the start of the system, nothing more. 
Btw this assisatant is really an absolute bullshit, if the length of input is the only 'criteria' for a sufficient  bug description.

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