git with ssh won't pull submodule

Getting the following error for a submodule when using git/ssh:

$ git clone --recursive ssh://incense:/home/erik/git/nacl.git Cloning into 'nacl'... remote: Counting objects: 32, done. remote: Compressing objects: 100% (25/25), done. remote: Total 32 (delta 5), reused 0 (delta 0) Receiving objects: 100% (32/32), 16.50 KiB | 0 bytes/s, done.

The git clone --recursive file:///home/erik/git/nacl.git works fine and pulls the submodule "crypto.git". Any ideas?

- The crypto.git is a valid repo.
- I have the correct permissions.
- The crypto.git repo is a git --mirror repo.
