Comment 18 for bug 1603186

From the symptoms it seems that the list of favorited scopes got messed up somehow. Did you uninstall unity-scope-click scope before at any point?

This list can be (re)set with e.g.
$ gsettings set com.canonical.Unity.Dash favorite-scopes "['scope://unity-scope-nearby', 'scope://clickscope']"`

or
$ gsettings reset com.canonical.Unity.Dash favorite-scopes

I think the problem we have is that on the phone we assumed click-scope would never be uninstalled (it's impossible to uninstall it via the UI) and therefore it's impossible to star/unstar it in the UI (it's always "starred"). If however the scope disappears from the system, it's also removed from favorites and there is no way to favorite it back even after manually installing the scope again.

Adding unity-scopes-shell as I think it needs to deal with the above scenario.
