207 Multi-Status response not parsed correctly

[tipa]

I am making a Propfind request like this:
var response = await client.Propfind("/some/file.name", new PropfindParameters());

This XML request is sent over the wire:

<?xml version="1.0" encoding="utf-8"?>
<D:propfind xmlns:D="DAV:">
  <D:allprop />
</D:propfind>

The server responds with 207 Multi-Status (which is unusual (most servers would return 404 - Not Found in this example) but probably within the WebDAV specs):

<?xml version="1.0" encoding="utf-8" ?>
<D:multistatus xmlns:D="DAV:">
<D:response>
<D:href>/some/file.name</D:href>
<D:propstat>
<D:prop>
</D:prop>
<D:status>HTTP/1.1 404 Not Found</D:status>
</D:propstat>
</D:response>
</D:multistatus>

I need to find out what status(es) the server responds with (detect the 404), but it appears like the PropertyStatuses field is not populated correctly:
