Comment 7 for bug 562380

By the way, your handle-patch-fix branch appears to be intact when upgraded manually. And your 'test-push' branch passes 'bzr check' as well. So no lasting harm appears to have happened to your repositories.

I'm about to submit a merge proposal that I believe fixes the root issue, which as discussed above is that "bzr branch lp..." should have failed for you in this case, because handle-patch-fix needed upgrading to match its stacked-on branch before it was usable.

I don't see any obvious reason from my investigations that would explain why the upgrade you tried via Launchpad's web interface failed. I'll add the launchpad-code project to this bug and see what those guys think.
