Another way to address this would be to remove the StartupWMClass and
StartupNotify keys from iceweasel.desktop. This results in not having
"application is launching..." feedback for iceweasel-started-as-iceweasel,
but the running process (when started as either iceweasel or firefox,
via the Shell or a terminal) is identified as Firefox; that seems a
reasonable compromise?
