command help for ginit and gtags not working

A 'bzr help ginit' or 'bzr help gtags' does not show the command help, but throws an error like this:

$ bzr help ginit
bzr: ERROR: exceptions.NotImplementedError: sorry, no detailed help yet for 'ginit'

*** 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
    attaching the crash file
        /home/atom/.cache/crash/bzr-20100126085918-10671.crash
    and including a description of the problem.

    The crash file is plain text and you can inspect or edit it to remove
    private information.

Is there really no detailed help for ginit and gtags? Then maybe a simple message output saying so would be more fitting than a crash report. Or is this a malfunction?

Crash file is attached.
