    Description

      I've tested this on Windows, Mac and Linux with 4.5.2 and on Windows with 4.6.0.

      To reproduce:
      1. Create a mapped network drive to some folder on another machine.
      2. Start up the "standardDialogs" qt example application.
      3. Turn off the "use native dialogs" option and bring up the dialog to find a file. This should come up quickly.
      4. Shut the dialog but keep the sample application running and then disconnect the other machine so that the mapped drive is unreachable. Don't just disconnect from the network on the machine running the test app though...disconnect the other computer.
      5. Now bring back up the file dialog. Now it should take around a minute to come up.
