[intrepid] bzr + dbus - X11 = pain

[GiuseppeVerde]

Binary package hint: bzr-dbus

When performing various tasks with bzr when I'm ssh'ed in, I get the following error:

*** 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.

Although things seem to work outside of the crashing, it still sucks. I think it's already caused some confusion in bzr (got a warning about the repository and files being out of sync and to please run bzr update)

Anyhow, bzr-dbus should fail gracefully if it can't get or launch d-bus, not crash and burn and potentially take my files with it.

This is fixed in the debian package.
