core: CalDAV-Error due to a location

The problem

Hi all,

Actually with the integration everything is working well but after restarting HA I realized the following problem with CalDAV. The thing is that suddenly no calendar data were loaded. Therefore I went to logs and got the following:

In the last line there is the parse error. What is really starnge for me is the fact that as soon as I delete the location from the corresponding event everything works fine again. Of course I have a lot of events with locations and only in some cases this error occur. In this case the address is as follows:

Taverna Georgios Kunigundenruhstraße 30, 96050 Bamberg, Deutschland

It seems the integration has a problem with locations.

The other strange thing is, that this event does not match the the search condition for the custom calendar.

Here’s the YAML:

calendar:
  - platform: caldav
    username: 'Marco'
    password: 'areallysuperpassword'
    url: https://my.syno.installation.de/caldav.php/Marco
    custom_calendars:
      - name: urlaub_marco
        calendar: "Gemeinsam"
        search: "Marco: Urlaub"
