*** Bazaar has encountered an internal error. This probably indicates a
    bug in Bazaar. You can help us fix it by filing a bug report at
        https://bugs.launchpad.net/bzr/+filebug
    including this traceback and a description of the problem.

[Matthew Fuller (fullermd)]

This is probably bug 830947.

Note that the problem happens during the build of the working tree, after the data is all downloaded. You can work around it via a "rm -rf * ; bzr revert" in the branch after it happens.
