Comment 8 for bug 773979

Totally breaks the user experience for many applications. An icon that behaves inconsistently is better than an application running in the background with no UI and no explanation to the user why it has apparently failed to start.

It also seems like ubuntu is going down it's own parallel world here.

If there is a need for this, why isn't freedesktop.org running with it? Seems application developers now have to choose or support both the standard way of doing things, and also the ubuntu way. Embrace and extend....
