Bug 50438 [RCP] Progress view icon "area" shows even if setShowStatusLine(false) is called
Build: M6 If I call IWorkbenchWindowConfigurer.setShowStatusLine(false) in my WorkbenchAdvisor's preWindowOpen(IWorkbenchConfigurer) method the status line is hidden. BUT, the action with a tooltip of "Double click to open Progress View" which appears in the bottom left of the window still shows. The action is missing/can't find its icon so it just shows as empty screen space, but it shows over views that I put on the left side of the window.

final MultiStatus status = new MultiStatus(IDEWorkbenchPlugin.IDE_WORKBENCH, 1, IDEWorkbenchMessages.getString("ProblemSavingWorkbench"), null); 
		IRunnableWithProgress runnable = new IRunnableWithProgress() {
			public void run(IProgressMonitor monitor) {
				try {
					status.merge(ResourcesPlugin.getWorkspace().save(true, monitor));
				} catch (CoreException e) {
					status.merge(e.getStatus());
				}
			}
		};
		try {
			new ProgressMonitorDialog(null).run(false, false, runnable);
		} catch (InvocationTargetException e) {
			status.merge(new Status(IStatus.ERROR, IDEWorkbenchPlugin.IDE_WORKBENCH, 1, IDEWorkbenchMessages.getString("InternalError"), e.getTargetException())); 
		} catch (InterruptedException e) {
			status.merge(new Status(IStatus.ERROR, IDEWorkbenchPlugin.IDE_WORKBENCH, 1, IDEWorkbenchMessages.getString("InternalError"), e)); 
		}
		ErrorDialog.openError(
			null, 
			IDEWorkbenchMessages.getString("ProblemsSavingWorkspace"), 
			null, 
			status, 
			IStatus.ERROR | IStatus.WARNING);
		if (!status.isOK()) {
			IDEWorkbenchPlugin.log(IDEWorkbenchMessages.getString("ProblemsSavingWorkspace"), status); 
		}
