Some background on this issue here:

Bert's talking about this change from the CHANGES file:
    * ra_serf: properly ask multiple certificate validation providers for
      acceptance of certificate failures (r1535532)

Which is this change:

I was under the impression that this didn't impact our command line client
because of the commit message that says we accept all or none of the failures.
 Looking at the code reinforces that view.

It's possible this change is somehow involved, but I'm not seeing how.

The X509_V_ERR_UNABLE_TO_VERIFY_LEAF_SIGNATURE error issue doesn't make any
sense in the context of a self-signed certificate so I really don't think this

Can you verify which version of serf you're using.  You can find this out by
running: svn --version -v

You'll get a lot of output but you're looking for this:
* ra_serf : Module for accessing a repository via WebDAV protocol using serf.
  - using serf 1.3.4
  - handles 'http' scheme
  - handles 'https' scheme

If you can do this with both the 1.8.5 and 1.8.8 version that would be
interesting.  I don't use MacPorts myself but it looks like the serf-1 package
can be independently upgraded from subversion.

We were discussing this on IRC and Lieven suggested that we ask that you
generate a new key/cert pair and send them to us so we can try and replicate
the behavior.  Because as things stand we're not sure what's wrong with the
certificate to trigger that other error.  Your httpd.conf details would
probably be helpful as well.
