TVB does not restart sometimes when started-clean from TVB_Distribution, or leaves two icons in the Mac-Bar

I reproduced this with package 1.1.

When started with package 1.1.2 tvb.app, the icon appears in the bar twice. When closing one of the applications in the bar, both processes are stopped.

When working with tvb_start.command from distribution 1.1.2, again the application appears twice in the bar (see attached screen also).
