git repository corrupted?

[Miika Turkia]

I just noticed that webgit doesn't give proper information and tried
to clone a completely new repository to verify:

---8<---
$ git clone git://subsurface-divelog.org/subsurface
Cloning into 'subsurface'...

warning: remote HEAD refers to nonexistent ref, unable to checkout.

Something is not working right.
