Comment 7 for bug 41828

At the very least this is causing a lot of "ubuntu dosnt work" comments its a VERY visible problem.

Best solution I can think of is to pass eveything back to gnome-app-install (which would need patching to accept command line package selections)......

So clicking on an install flash bar would open
gnome-app-install flashplugin-nonfree

From there i guess its just a question of matching mime types to packages...
