Invalid access to memory upon connecting via WebDAV

Trying to connect to an instance of eXist-database behind httpd-reverseproxy via WebDAV, I get the error -see below.
It is possible to connect this way in Oxygen (XML-Editor), so basically the setup seems to be working.
I was also able to connect to a local instance of eXist via WebDAV.

best,
