OVERVIEW
My aim is to develop a Python application running on a Raspberry Pi which reads OwnCloud calendar entries over the network. The calendar itself is part of a local installation of Owncloud which resides on another Raspberry Pi within the same local network. Access is done via HTTPS without active SSL authentification when doing the request.
PROBLEM
I tried to use the caldav Python package. After installation of the package using PIP and Python v2.7, I get an Exception: The CalDAV server you are using has a problem with path handling.
This is what I typed into PYTHON IDLE v2.7:
import caldav
cal_user='user'
cal_pass='pass'
cal_url='https://192.168.1.46/remote.php/caldav/calendars/user/pers%C3%B6nlich'
cal_client=caldav.DAVClient(cal_url, username='user', password='pass', ssl_verify_cert=False)
cal_principal=cal_client.principal()
And this is what was printed on the console:

Exception: The CalDAV server you are using has a problem with path handling.
I've tried to play with the URL as much as possible to eliminate any possible typing errors on my side, but I am still not 100% sure I managed to do it right.
Does somebody have a practical explanation for the final exception message in my case? Where could I proceed looking for a solution to my problem?
I was able to reproduce your problem. The solution was to change the calender's name in the URL from
pers%C3%B6nlich to pers%c3%b6nlich
Mind the case of the B and the C.
