I have multiple calendars. Local .ics files as well as remote .ics files via webdav.

When trying to "move" (via context menu) an event from one calendar ("cal1") to another (cal2) I get an error message and the event is copied instead.

The error message reads as follows:
"Das Ereignis „test“ kann nicht von calendar1 entfernt werden. Jedoch wurde eine Kopie in calendar2 abgelegt." 
(translates to something like: "The event "test" could not be deleted from calendar1. Anyway a copy was stored in calendar2.")

Deleting the event from calendar1 afterwards works without problems (after confirming the deletion in a dialog box).

It does not seem to matter if I move between local or remote calendars or mixed. It's always the same behaviour.

Reproducible: Always

Steps to Reproduce:
1) Create two calendars "cal1" and "cal2". Can be local or remote.
2) Create an event in cal1.
3) Right click the event in any view (week, month, time line or list view) and select "move to calendar / cal2"


Actual Results:  
1) I get an error message saying that the event could not be deleted from cal1.
2) The event is copied to cal2.

Expected Results:  
The event is moved to cal2 without an error message.
