*** 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.

bzr.dev r3267 (same in r3266), bzr-svn 0.4 r948 (same in r947), Ubuntu 7.10.

Note that it doesn't crash without --scheme, but thanks to a "wiki"
directory, it's interpreted as one big branch instead of
trunk/branches/tags.
