Not a problem.

Now that I see the problem, I can repro it very easily, too :-)

Excellent. You rock. This keyed me right in on the problem. I wasn't seeing
the fault because my deletions of collections were succeeding. You were
running into some kind of error, and BAM! :-)

The basic issue is that dav_add_response() assumes a certain value in
wres->walk_ctx which isn't being filled in when a deletion occurs. It isn't
supposed to, so dav_add_response needs to change.
[ this bug was introduced when I cleaned up the walk structures and handling
  a couple months ago ]

Fix coming momentarily...
