error: * Ignoring funny ref 'refs/heads/' locally

Can someone tell me why this happens?

error: * Ignoring funny ref 'refs/heads/' locally

It also happens with 1.6.3.1

$ mkdir root
$ cd root
$ git init
Initialized empty Git repository in /tmp/root/.git/
$ :> .gitignore
$ git add .gitignore
$ git commit -m "initial"

$ cd ..
$ git clone root clone

$ cd clone
$ git fetch origin :
error: * Ignoring funny ref 'refs/heads/' locally
$ git --version
git version 1.6.0.4
$ exit

Previously, the refspec "<src>:" would be expanded to "<src>:refs/heads/". Instead, treat an empty <dst> just like refspecs without a colon.

This fixes it.

Note that "git fetch origin :" is short for "git fetch origin HEAD", which stores the remote HEAD in FETCH_HEAD. You probably want "git fetch origin", without an explicit refspec, which defaults to "git fetch origin 'refs/heads/*:refs/remotes/origin/*'", i.e. store remote branches in the namespace for tracking branches.
