Comment 7 for bug 280595

So, as best as we can tell, the Launchpad bug was occurring because Bazaar was making broken branches (see bug 291046). This bug has been fixed in bzr.dev and should be in Bazaar 1.11, which means that we can expect the number of branches created this way to go down.

Although it's conceivable that we could do something server side to fix existing broken branches, and also to fix incoming broken branches, I don't think we want to spend that much effort working around the GIGO rule.
