Another bzr-externals failure. Any ideas about this?

[Patrick van der Velde]

Hi All

here's another one. I was trying to setup an externals and got an
error (stack trace follows). Then when I tried again I got an error
saying something about packs that already existed (see end of email).
Any ideas or is this another bug report in waiting?
