Application: plasmashell (5.9.3)

Qt Version: 5.7.1
Frameworks Version: 5.31.0
Operating System: Linux 4.10.4-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
Looking at the different options to configure digital clock settings.  I first changed the format to show date and 24-hour clock.  I applied changes, then looked through the other tabs on the left side.  The application crashed specifically after looking at calendar.

- Unusual behavior I noticed:
Before the crash, I had no calendars under "PIM Events Plugin" and no options under "Calendar."  After the crash, I was unable to reproduce the error, but I noticed that I have access to the default calendars under PIM Events Plugin (Birthdays & Anniversaries, Personal Calendar) and I have checkboxes available under Calendar.  I wonder if this bug is related to me not having set up Kontact or my PIM yet.

- Custom settings of the application:
Kontact/PIM not yet set up.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
