I can confirm this problem on plain old ext3.
whenever git has to work on ecryptfs, symlinks fail.
I cannot add new symlinks, and all old ones(when I clone an existing repo) permanently stay in a 'modified' state.

Error reading symlinks in an ecryptfs filesystem

Bug description:
Binary package hint: libecryptfs0

The problem shows up in Git, though I don't think it is a Git problem (though I could be wrong). The issue is that when Git tries to read a symlink on an eCryptfs filesystem, it fails with:

error: readlink("link-to-file"): Invalid argument
error: unable to index file link-to-file

I can confirm that it works on my ext4 root partition, and it has worked in the past, so I'm fairly sure it is an eCryptfs issue.

I have attached a script which demonstrates the problem. It creates a folder "test" in the current directory, initiates a git repository, adds a file and a link to that file. Here is what the output looks like for me:

(/ is an ext4 partition and my home folder is eCryptfs)

  $ cd /tmp
  $ sh ~/test-script.sh

    Initialized empty Git repository in /tmp/test/.git/
