Bug 411378

Application: akonadi_davgroupware_resource (5.12.0)

Qt Version: 5.13.0
Frameworks Version: 5.61.0
Operating System: Linux 4.12.14-lp150.12.70-default x86_64
Distribution: "openSUSE Leap 15.0"

-- Information about the crash:
- What I was doing when the application crashed:

The dav groupware resource (for a nextcloud server) showed "could not connect to host" ... status,
so I decided to do a restart (from akonadiconsole), which led to the crash

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