per the LF folks, I removed a hyphen in the $URL, but then still die thus:

[Andrew Bennetts (spiv)]

You're using a beta version of bzr 2.1. This was fixed in the final release of 2.1.0, so upgrade your bzr to a newer version.

[Martin Pool (mbp)]

This is a dupe of bug 636930.

[herrold (herrold)]

I confirm an update solved the reported matter for me

[herrold@centos-5 pw]$ rpm -q bzr
bzr-2.3-0.1.b2orc

I am all-right with a close of this bug as it seems the underlying matter is understood
