Bug Description

Binary package hint: unity

Let's say an application creates a LauncherEntryRemote via libunity on application startup. The current code notices new LauncherEntryRemote objects, checks if there is a matching icon, and then puts the two together.

That works great if the LauncherIcon was created before the LauncherEntryRemote object. But if it's the other way around, the current code never thinks to look for already-existing LauncherEntryRemote objects when bamf finally does notice a window.

I'll have a branch to file soon.
