UnicodeDecodeError when reporting problem starting external editor

[ZeWaren]

Here is what happened:
My Windows is in French, but the files don't have accents in their names.

*** 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.

[Martin Packman (gz)]

You have one of the environmental variables BZR_EDITOR, EDITOR, or VISUAL, or editor set in the bazaar.conf file, to either a non-existent path or a path with a space in it. The spaces issue has just been fixed in bug 220331, but finding and changing the problem path will be necessary for now.

This particular bug is due to bad logging of the exception instance in bzrlib.msgeditor._run_editor which incorrectly uses `str(e)` when the error message may contain non-ascii characters on some systems, and bug 273978 covers the overall problem.
