git checkout <branch_name>

The repo isn't public, I'm afraid.

I should mention what *exactly* happened that led to this. I was trying
to publish my branch on Launchpad (using git-remote-bzr). At some point,
I had the genius idea to remote the extra stuff from the config file and
just try with the bzr:: remote as origin, and instead of doing it via
the console, I just replaced the config file.

Annnnyway, I just restored my backed up config file for that submodule
in the middle of writing this and seems like things seem to work now.

I dunno, this was most likely because of some configuration derp on my
part (the new config file didn't contain the branch information most
likely). So I guess problem solved!

Thanks for your help.
