I've had this problem very often.

I suspect its because when you're in detached head state, the description of the "head" is something like foobar^

So of course, making a branch like build/foobar^ results in git going "Wat? cr... a branch, but the branch name is a head, d... NOPE".

My solution to this is to hack around travis's weird behaviour, by aggressively trying to make the git repository appear identically to how it did when the commit occurred.

Yeh, you'll see I'm also walking the branches for tags to nuke tags that are newer than the commit, because travis will still fetch those tags and git will still see them, so anything tag based will have fun times too!

Also, this appears to be the second time you've reported the same bug :)

I'm not 100% sure if it's the same bug as then. I think it's just the same symptom. I certainly wasn't using travis then. -- Caleb Cushing http://xenoterracide.com Calendar: https://www.google.com/calendar/embed?src=xenoterracide%40gmail.com&ctz=America/Chicago
