title: Cloning a git repo succeeds with the command line, but fails with a git GUI client (e.g. SourceTree)
body: <p>I've set up a <code>git</code> user on a Mac OSX 10.7 system. In the git user's root, I've created a <code>repositories</code>  folder and initialized a bare git repo named <code>test</code>.</p>
  
  <p>So far so good. Now, I clone the repo from a PC on the same network as the Mac with</p>
  
  <pre><code>git clone git@mac:repositories/test.git
  </code></pre>
  
  <p>This succeeds. I can then, push and pull from this repo. All looks good.</p>
  
  <p>But, when trying to do the same thing with Atlassian SourceTree - a GUI git client - <strong>this fails</strong>: </p>
  
  <pre><code>This is not a valid source path / URL
  </code></pre>

  <p><strong>Anyone an idea what I might be doing wrong?</strong></p>
