tl;dr:

- `git bundle create` without <git-rev-list-args> gives git rev-list
help, then dies.
   Should point out missing <git-rev-list-args> instead.
- `git clone <bundle> <dir> gives "ERROR: Repository not found."
- `strace ... git clone <bundle> <dir>` (magically) appears to work but
   cannot checkout files b/c of nonexistent ref.
- Heisenbug? Race condition?

Full description:

When I try to clone from a bundle created from a local repository, `git
clone <bundle> <dir>` fails with: "ERROR: Repository not found. fatal:
Could not read from remote repository." unless I run it with strace.

OS: Arch Linux (rolling release)
Git versions: 1.8.1.3 and git://github.com/git.git master@02339dd

Steps to reproduce:

For those who like to "save the trees" (source code or otherwise), here 
is a much simplified test case:

$ # Create test repository with a single commit in it
$ mkdir testrepo
$ cd testrepo
$ git init
$ echo Test > test.txt
$ git add test.txt
$ git commit -m "Add test.txt"

$ # Create bundle
$ git bundle create ../testrepo.bundle master

$ # Try to clone from bundle
$ cd ..
$ git clone testrepo.bundle testrepofrombundle

$ # Clone from bundle, wrapped with strace
$ strace -f -o /dev/null git clone testrepo.bundle testrepofrombundle

$ # Examine cloned repository
$ cd testrepofrombundle
$ ls
$ git branch -av
$ git checkout master
$ git branch -av
$ # Where's my HEAD?

Kind regards,
