git fetch origin hanging in 1.7.0

Hi,

I've run into an issue that doing a "git fetch origin" is hanging for me in git 1.7.0. The setup here may be wrong, so I don't want to call it a bug. But basically I have an empty repo created on the server that a client then clones. There's a job that fetches new updates to the server periodically. If nothing has been pushed to the server yet, the client fetch hangs.

This worked fine in 1.6.6, so I'll just roll back my version for now. But any help on how to do this different would be much appreciated.
