That sounds like progress. I was hoping I could replicate it with that information, but I still can't:

  LOCAL_GIT=git.v2.5.0
  REMOTE_GIT=/home/peff/compile/git/bin-wrappers/git

  $ $LOCAL_GIT version
  git version 2.5.0

  $ ssh git.peff.net $REMOTE_GIT version
  git version 1.7.0.4

  $ ssh git.peff.net "rm -rf /tmp/foo.git; $REMOTE_GIT init --bare /tmp/foo.git"
  $ GIT_DIR=$PWD/.git GIT_WORK_TREE=$PWD $LOCAL_GIT push \
      --receive-pack="env | grep GIT >&2; $REMOTE_GIT receive-pack" \
      git.peff.net:/tmp/foo.git HEAD:branch

  GIT_DIR=/home/peff/tmp/.git
  GIT_WORK_TREE=/home/peff/tmp
  GIT_PREFIX=
  Counting objects: 3, done.
  Writing objects: 100% (3/3), 208 bytes | 0 bytes/s, done.
  Total 3 (delta 0), reused 0 (delta 0)
  To git.peff.net:/tmp/foo.git
   * [new branch]      HEAD -> branch

Interestingly, if I try pushing straight to master, the remote side complains about trying to push the checked-out branch, even though it's a bare repo (presumably it's getting confused by the GIT_WORK_TREE setting; so that's _a_ bug, but not the one you are seeing).

So I'm not sure what is different about my setup and yours.
