error pulling from svn repo - unable to handle http code 401

[Gary Wilson Jr.]

Recently upgraded my laptop to 10.04 and having issues with an
existing bzr branch from a svn repo from before the upgrade.  Trying
to pull updates results in things hanging for a while, then finally
coming back with the following error:

$ bzr -Dtransport pull
Using saved parent location: https://server.com/repos/proj/trunk
bzr: ERROR: Invalid http response for
https://server.com/repos/proj/trunk/.bzr/branch-format: Unable to
handle http code 401: expected 200 or 404 for full response.

This works on my other machine that I updated to 10.04.  Any ideas as
to what's going on here?

FYI, the bzr log looks like this:
