Webapps not acessible from another Workspace with firefox

[Andre Lacerda]

Ubuntu 12.10, Firefox 19

Open firefox and a webapp like gmail for instance. Go to another workspace, click the webapp icon on the laucher it will get you back to the workspace where firefox is and get you into the gmail webapp.

Now go to another workspace, open another window, like nautilus, for instance and click the webapp icon on the laucher. It won't get you back to the gmail webapp, it will only "shake" the firefox icon and nothing will happen

It should get you back to the workspace where firefox is open with the webapp
