Bug 378474

Application: plasmashell (5.9.4)

Qt Version: 5.7.1
Frameworks Version: 5.32.0
Operating System: Linux 4.10.8-gentoo x86_64
Distribution: "Gentoo Base System release 2.3"

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

I was checking some clock settings, restarted Akonadi to see whether I could get the clock's calendar to display my events, when suddenly Plasma crashed.

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