title: QProcess Mac OS , Cant launch executable with arguments
body: <p>/usr/local/bin/rdesktop  launched from terminal connects me to host</p>
  
  <p>following launches rdesktop without arguments:</p>
  
  <pre><code> QString program = "/usr/local/bin/rdesktop";
      QStringList args;
      QProcess *process = new QProcess(this);
      args &lt;&lt; m_address;
      process-&gt;start("open \""+program);
      process-&gt;setArguments(args);
  </code></pre>
  
  <p>have tried with same result:</p>
  
  <pre><code>process-&gt;startDetached("open \""+program);
  process-&gt;execute("open \""+program);
  </code></pre>
  
  <p>also with arguments overloaded func process.start("open \""+program, args)
  and it doesnt launch anything and no error message either.</p>
  
  <p>some advice please?</p>
