Bug 357925

Application: akonadi_googlecalendar_resource (4.89.0)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-23-generic x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
- Unusual behavior I noticed:
Akonadi crashes with google calendars + compositor of my KDE5 is strange, I had to use xrender.
May be not related though.

The crash can be reproduced every time.

-- Backtrace:
Application: Zdroj Akonadi (akonadi_googlecalendar_resource), signal: Segmentation fault
