[Evolution] Bug#876781: Since upgrade to Evolution 3.6.0-1 in Debian Buster caldav-events cannot been creted/edited/deleted

[Bernhard Hohensinn]

Package: evolution-data-server
Version: 3.26.0-1


Hello,

I am using Debian Buster and my calendars are on a Nextcloud-Server,
Version 12.0.3 on a Raspi. The calendars fo the Nextcloud are connected
to Evolution via Caldav. In Evolution 3.26.0-1 all events are shown
correctly, but when I want to create/edit/delete an event of one of
these calendars, I get the following message:

'Kalenderobjekt kann nicht verändert werden: Daten konnten nicht
gesendet werden: HTTP-Fehlercode 415 (Unsupported Media Type):
Sabre\DAV\Exception\UnsupportedMediaType
  This resource only supports valid iCalendar 2.0 data. Parse error:
End of document reached prematurely[exception][message]'

I can create/edit/delete events on these calendars on my Android
smartphone as well as when I use Thunderbird on Debian Buster.

regards,

Bernhard
