title: Missing icons in QTabWidget
body: <p>I'm using the newest Qt 4.5 and I'm creating my GUI with Qt Creator. My tab widget looks fine in the Creator, with all icons displayed. However, when I compile it and run it, there are no icons, but the tabs are wider than they are which indicates something, obviously. I tried both .png and .ico formats, none work. The size of icons is 16x16, exactly as the maximum tab icon size property.</p>
  
  <p>The stylesheet to the tab control is not applied (nor there is any), except the 'general style' which is 'clearlooks'.</p>
