Application: kontact (5.6.0) Qt Version: 5.9.1 Frameworks Version: 5.37.0 Operating System: Linux 4.4.79-19-default x86_64 Distribution: "openSUSE Leap 42.3" -- Information about the crash: Switching from mail to calendar in contact, after a few seconds the application crashes. Manually removing the DAV resource makes the calendar operational again, but without the remote calendar of course. I can recreate the DAV resource (for accessing an owncloud calendar) in the calendar, but as soon as I switch to another program in kontact (e.g., mail) and back to the clanedar, it crashes again. The crash can be reproduced every time. -- Backtrace: Application: Kontact (kontact), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

P.S.: The problem may be more related to displaying events in the standard calendar rather than fetching them through the DAV resource. Two arguments: 1) In aconadiconsole, which probably uses the same resource, the calendar items look alright. 2) When clicking on the eye icon next to the calendar in kontact/korganizer (with the resource itself disabled), the calendar also shows alright in the pop-up window that appears. Only if the resource is enabled (in the checkbox at the left), the program crashes.
