title: When opening a directory through command line, Sublime text opens two windows instead of one
body: <p>If I open a directory in Sublime using the command line (<code>subl path/to/my/folder/</code>), Sublime will open two instances: one with the directory I asked for, and another one with the directory I opened last time I used Sublime.  Any idea why ?</p>
  
  <p>I don't know if it's revelant, but the problem occurs with Ubuntu 12.04.</p>
