	 * FIXME: This is a workaround for a quite odd problem:
	 * When starting up kopete and the msn plugin gets loaded it can bring up
	 * a messagebox, in case the msg configuration is missing. This messagebox
	 * will result in a TQApplication::enter_loop() call, an event loop is
	 * created. At this point however the loop_level is 0, because this is all
	 * still inside the KopeteApplication constructor, before the exec() call from main.
	 * When the messagebox is finished the loop_level will drop down to zero and
	 * TQApplication thinks the application shuts down (this is usually the case
	 * when the loop_level goes down to zero) . So it emits aboutToQuit(), to
	 * which KApplication is connected and re-emits shutdown() , to which again
	 * KMainWindow (a KopeteWindow instance exists already) is connected. KMainWindow's
	 * shuttingDown() slot calls queryExit() which results in KopeteWindow::queryExit()
	 * calling unloadPlugins() . This of course is wrong and just shouldn't happen.
	 * The workaround is to simply delay the initialization of all this to a point
	 * where the loop_level is already > 0 . That is why I moved all the code from
	 * the constructor to the initialize() method and added this single-shot-timer
	 * setup. (Simon)
	 *
	 * Additionally, it makes the GUI appear less 'blocking' during startup, so
	 * there is a secondary benefit as well here. (Martijn)
