review: Needs Resubmitting

[Marco Trevisan (Treviño) (3v1n0)]

So, sorry for the big delay.

I've finally reviewed this bug, this fix breaks the fix for lp:692462, and we really don't want it.

Basically running "chromium-browser --app=http://google.com" with this causes to get a floating window with no related application icon at all.
