After some more debugging, I find that the problem is the URI comparisons in
that function. On one side, the HA2 digest contributor has been calculated
using the actual URI of the PROPFIND request (.../!svn/rvr/...). On the
side of the comparison, a bit of path information is pulled from the Serf
connection's host_info structure. All works well for the OPTIONS requests,
which both hit the public URI of the repository. But that PROPFIND comes
along and the comparisons fail.

I'll need to take this up with the Serf developers.
