Operating System: Linux 5.2.14-arch1-1-ARCH x86_64

-- Information about the crash:
- Unusual behavior I noticed:

Desktop doesn't appear at all, it just crash when Plasma Shell starts.
It seems related to calendar plugin but it worked before...

The crash can be reproduced every time.

For further details: it happened when i configured the plasmoid "Event Calendar" to show holidays, when i checked the option, the whole stuff crashed.
