Unable to access CalDAV/CardDAV

[Henning]

Hi,

I wanted to bring up this iRony error again. It reports

<d:error><s:exception>Sabre\DAV\Exception\NotFound</s:exception><s:message>Addressbook
with name '3f986cb59640-5a5fae4588d8-90a37809' could not be
found</s:message><s:sabredav-version>1.8.8</s:sabredav-version></d:error>

Should I open a bug report?
