commit c8e45b10c32679bf070af5b7ad9a22b91eb9a02c
Author: Sergio Martins <iamsergio@gmail.com>
Date:   Mon Sep 12 13:48:33 2011 +0100

    Fix crash on agent_launcher exit.
    
    Don't unload plugins here. They will be unloaded on application exit,
    so it's redundant.
    
    Seems they are being unloaded too early, before QThreadStorage
    cleanup occurs:
