User reports that if he adds a recurring event it crashes the plugin. Log below. (I have asked for additional information regarding where the event was created (outlook, owncloud,or android)

Owncloud returns 500 Internal Server Error, so you have to check the owncloud server logs to see what caused the error.

You can also Download http://sourceforge.net/projects/outlookcaldavsynchronizer/files/1.2.1.Logging/CalDavSynchronizer.zip/download , which will write the server response in the logfile.

@nertsch commented on GitHub (Sep 23, 2015):

The logfile says, that this error happens, when CalDavSynchronizer tries to fetch the events from CalDAV. Synchronization didn't even start.

That seems to be a Bug in SabreDav.

Maybe caused from an event in Owncloud with INTERVAL=0, a every workday recurrence wrongly synced from Outlook, see https://github.com/aluxnimm/outlookcaldavsynchronizer/issues/99

Fixed from our side in latest commit, will be in next release.
