Application: korganizer (5.9.3)

Qt Version: 5.11.1
Frameworks Version: 5.52.0
Operating System: Linux 4.19.6-300.fc29.x86_64 x86_64
Distribution: "Fedora release 29 (Twenty Nine)"

-- Information about the crash:
- What I was doing when the application crashed:

I created an event with multiple participants and pressed "Apply". KOrganizer crashed in reaction to this, but appears to still have created the event.

-- Backtrace:
Application: KOrganizer (korganizer), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
28	  return SYSCALL_CANCEL (nanosleep, requested_time, remaining);
