I found that into the last version of Davical, all events are sent within CDATA string.

For example :

<![CDATA[BEGIN:VCALENDAR
VERSION:2.0

This is specified into the RFC 4791 :

The iCalendar data embedded within the CALDAV:calendar-
timezone XML element MUST follow the standard XML character data
encoding rules, including use of &lt;, &gt;, &amp; etc. entity
encoding or the use of a <![CDATA[ ... ]]> construct.  In the
later case, the iCalendar data cannot contain the character
sequence "]]>", which is the end delimiter for the CDATA section.

Agendav does not strip this strings when passing the events to iCalcreator for parsing. The result is that iCalcreator does not recognized at all the first line of the event, and return FALSE.

I suggest a workaround into Davical (https://github.com/DAViCal/davical/pull/6#issuecomment-17223279), but I think that this issue should be fixed into Agendav.
