Following your link I found https://github.com/owncloud/calendar/issues/1002 and the second comment has a solution that fixes the problem for me. I did a vimdiff on his file and without understanding much I can tell you that the changes look reasonable. I have only been testing for 5 minutes but so far it works.
multiple ics for tasks
i am seatching this forum but found nothing about this constellation.
i have an Axigen Mailserver running and would like to add my tasks into Davdroid.
The problem is: i like to make categroies in my tasks und now i have mutiple *.ics
Is there an option in Davdroid for that? Is it possible to add:

Or have i make some xtra accounts for each ics…
