title: Opening ipython from sublime text
body: <p>I added the following plugin to sublime text 2 which is meant to open the ipython qt console:</p>
  
  <pre><code>import sublime, sublime_plugin
  from subprocess import call
  # import os
  
  class ipythonQtCommand(sublime_plugin.TextCommand):
      def run(self, edit):
          call(["start","ipython", "qtconsole", "--pylab", "--ConsoleWidget.font_size=9", "--ConsoleWidget.font_family='Consolas'"],shell=True)
  </code></pre>
  
  <p>Initially it worked just fine, i.e. the plugin opened an ipython shell. I then added a menu item and a key binding. At some point something must have gone wrong since now I get this error when I run the plugin:</p>

  <p>I tested the script by running it line by line in the st2 shell itself and it is the last line <code>call([...])</code> that causes the error. I find this a little strange since the command works ok when calling it from somewhere else, e.g. ipython itself.</p>
