Description nonof 2016-11-12 07:54:59 UTC

Application: plasmashell (5.8.3)

Qt Version: 5.7.0
Frameworks Version: 5.27.0
Operating System: Linux 4.4.31-1-lts x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
Booted into plasma, hadn't opened anything at that point. Clicked on the digital clock on the panel to show the calendar events. Immediately upon clicking, Plasma crashes. In fact, right now, impossible to check the calendar events via digital clock. Plasma just crashes every time. However, Kontact (and Korganizer) work fine.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/usr/lib/libthread_db.so.1".

I have been playing with the settings and was able to narrow it down a bit.

If in calendar the following options are enabled/disabled:
- Show week number
- Holidays
- Pim Events Plugin

Everything works.

The problem is the PIM Events Plugin. Enabling the calendars in there will cause the described bug. I have just disabled all calendars under the PIM events plugin and now everything is working again. I don't know whether it is useful, but just in case: my calendars are a DAV resource (CalDAV).
