Gnome 3.16.2 introduce a strange problem in the dash

[Donato Marrazzo <donato marrazzo gmail com>]

I noticed a strange problem that seems to affect just vmware.

I have the vmware icon in the dash as favourite application.

It happens that if I launch vmware and then I move the window to an other workspace, I get two vmware icon in the dash one "inactive" that launch a new app instance and one for the active application.
