The plugin 'seek' could not be loaded

[robt105]

While installing, everything went fine until the "Tick the check-box to enable it."
Then I get:
The plugin 'seek' could not be loaded
An error occurred: Plugin loader 'python' was not found

I have both python and python3 loaded.
I tried updating seek.plugin to use python3, still no go.

I'm running Fedora 22, 64-bit, GNOME 3.16.2.
Rhythmbox 3.2.1

Any ideas?
