Description Markus Grabner 2017-07-27 00:32:21 UTC 
Application: akonadiserver (5.5.2)

Qt Version: 5.6.2
Frameworks Version: 5.32.0
Operating System: Linux 4.4.76-1-default x86_64
Distribution: "openSUSE Leap 42.3"

-- Information about the crash:
Ca. 30 seconds after starting kontact, the akonadi server crashes without further user interaction. On startup, kontact displays the calendar page with ca. 10 calendars, most of them CalDav. This behaviour is new in openSUSE Leap 42.3, kontact+akonadi worked fine in earlier versions.

The crash can be reproduced every time.

-- Backtrace:
Application: Akonadi Server (akonadiserver), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
