[horde] Problem with CalDAV/WebDAV

[Dominik Erdmann]

Hello,

I have problems with reading my standard calendar in 
Thunderbird/Lightning with CalDAV and WebDAV/ICS.

If I open the CalDAV address in a browser, I get the answer:

<d:error xmlns:d="DAV:" xmlns:s="http://sabredav.org/ns">
   <s:exception>Sabre\DAV\Exception</s:exception>
   <s:message>Der Termin konnte nicht ausgewertet werden.</s:message>
   <s:sabredav-version>1.8.6</s:sabredav-version>
</d:error>

The answer of the ICS address is the following:
(see attached file)

There are no SYSLOG entries.

I created a new calendar with a single event. With this one I get the 
expected results.


In my live environment I observe a similar problem. But the request of 
the CalDAV/WebDAV address runs and runs and never ends. I don't get any 
answer.

How can I identify what the problem is and especially how can I fix it?


Thanks a lot
Dominik
