[horde] H6 CalDAV client fails with error code 500

[Horst B Simon]

Hi,

When I connect with the Caldav I get following error on the client:

The calendar “Calendar of Horst B Simon” failed to update with an unexpected error.

The request for “Calendar of Horst B Simon” in account “Hbsimon” failed.

The server responded with
“500”

The horde log shows following:
	SELECT type_id, type_name FROM `rampage_types` WHERE type_name IN
	  ('contact') [pid 1056 on line 244 of "/opt/local/www/apache2/horde/vendor/horde/db/lib/Horde/Db/Adapter/Pdo/Base.php"]
