Description Richard Lee 2017-09-03 20:33:50 UTC 
Application: kontact (5.6.0)

Qt Version: 5.9.1
Frameworks Version: 5.37.0
Operating System: Linux 4.4.0-93-generic x86_64
Distribution: KDE neon User Edition 5.10

-- Information about the crash:
- What I was doing when the application crashed: Attempting to view two calendars side by side. Each time I try, Kontact crashes. I am using akonadi-ews if that matters.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
