No, what you're doing should work OK (though it does actually produce
ugly "the remote end hung up unexpectedly" messages in v1.6.6).
I can reproduce the bug with:
$ mkdir foo && (cd foo && git init)
$ git clone foo bar
Initialized empty Git repository in /home/peff/bar/.git/
warning: You appear to have cloned an empty repository.
$ cd bar && git fetch
which hangs on a pipe read(). It bisects to 61b075b (Support taking over
transports, 2009-12-09) from Ilari (cc'd). It looks like we get the
empty ref list once in get_remote_heads, and then try to get it again
and hang. Maybe we need this?

That fixes the problem for me, but I am totally clueless about this
code. Do all transports have a git_transport_data (if so, then why is it
a void pointer?).
