I think the problem is the fact that bzr-svn doesn't pick up the
username. bzr-svn doesn't support usernames in urls at the moment (it
passes the url on verbatim to subversion, which doesn't support it).

You can do two things to fix this:

* Make sure svn caches the username for the repository. This should be a
matter of running "svn proplist
https://papyrus.usask.ca/svn/dept/gt/trunk/" without the --username
argument. Subversion will ask you for the username and should cache it.

* Install a recent Subversion 1.5 snapshot and use bzr-svn 0.4.6. In
this situation, bzr-svn should prompt you for a username/password
combination.

Cheers,

Jelmer
