*** Bazaar has encountered an internal error.
    Please report a bug at https://bugs.launchpad.net/bzr/+filebug
    including this traceback, and a description of what you
    were doing when the error occurred.

So the problem is not with the protocol since HTTPS and SSH behave the same, the problem is with something in bzr-svn interpretation of things in the Subversion repository -- but I am guessing.
