rocketfuel-setup can't resume if fails to complete

I also got the following upon completion of this script... So still don't have a working development branch just yet!

utilities/shhh.py python2.4 bootstrap.py --ez_setup-source=ez_setup.py \
  --download-base=download-cache/dist --eggs=eggs
utilities/shhh.py ./bin/buildout configuration:instance_name=development

Thank you for using this script. You can improve it for everyone by
committing changes to Launchpad in utilities/rocketfuel-setup.

Please see http://dev.launchpad.net/ for more information on
developing and testing Launchpad, and on submitting changes.

You can use the following commands to manage your Launchpad
development environment:

 rocketfuel-get
    Update your copy of devel and the necessary source
    dependencies, and make sure all source dependencies are properly
    linked in to all the branches you are working on.

 rocketfuel-branch foo
    Create a new branch of LP called "foo" in
    /home/scott/launchpad/lp-branches/foo,
    with all the source dependencies properly linked in.

 rocketfuel-status
    Check each of the branches in /home/scott/launchpad/lp-branches
    and show which of them have uncommitted changes; also check which ones
    have revisions that have not yet landed on trunk.

 rocketfuel-push
    Push all of your branches to Launchpad, so that you have a server-side
    backup of everything.

Happy hacking!

I can confirm this. When the branch command is interrupted, it won't resume correctly.

The linked branch contains a fix for this. It checks if the branch was successful.

Scott, this is fixed in the latest version of rocketfuel-setup. It would be nice, if you could test it:
- run rocketfuel-setup and abort the branch command, this is when it says: "Making local branch of Launchpad trunk, this may take a while..."
- run rocketfuel-setup once again and you should get a message explaining what to do next
