Bug#766426: Dolphin search displays "Invalid protocol" error.

[Brendon Higgins <brendon@quantumfurball.net>]

For the benefit of those, like me, who encounter this problem with a recent 
install, note that the solution has changed since the transition in Testing to 
KDE Frameworks 5: don't install baloo4, it won't work with current dolphin. 
Instead, install baloo-kf5.

Maintainers, please consider making plasma-desktop (or some package you think 
is more appropriate - perhaps dolphin) at least recommend baloo-kf5. From what 
I can tell, right now, nothing even suggests baloo-kf5, and it's rather opaque 
to an ordinary user that this package might be necessary for some standard 
functionality.

Peace,
Brendon
