title: Can't "pull" with smartgit, "fetch only" is available
body: <p>I use <strong>SmartGit</strong> as a GUI for git. But so far, I always have the same problem.
  In my projects (all of them), <em>I can't pull</em>, the button is disabled, it's only the "fetch only" button which is available.</p>
  
  <p>But if I run the command <code>git pull origin master</code> it <em>works fine</em> and I can continue to use SmartGit as usual.</p>
  
  <p>How to get rid of this problem ?</p>
