title: Can't manage to load my private key with git extension
body: <p>I've been trying for the last 2 hours.
  I'm using xp-dev as a git repository provider (because I'm already paying and I have svn repo over there)
  I've given xp-dev my public key.</p>
  
  <p>But when cloning my repo I a being rejected.</p>
  
  <pre><code>"C:\Program Files (x86)\Git\bin\git.exe" clone -v --recurse-submodules --progress "ssh://xp-dev.com/repogit" "c:/ProjetPerso/repogit"
  Cloning into 'c:/ProjetPerso/repogit'...
  Permission denied (publickey).
  fatal: Could not read from remote repository.
  
  Please make sure you have the correct access rights
  and the repository exists.
  Done
  </code></pre>
  
  <p>And from what I understood from various blogs, git extension should ask me to load my private key, except it doesn't.</p>
  
  <p>I tried launching the putty authentification client (even though I choose openSSH) and loaded my private key inside, but it changes nothing.</p>
  
  <p>Any ideas?</p>
  
  <p>Thanks.</p>
