[Evolution] Enabling Evolution RSS Reader Plugin

[Mason Hock <masonhock gmail com>]

Hi,

I am running Evolution 3.10.4 on Trisquel 7.0. I have downloaded
Evolution RSS Reader Plugin by installing evolution-rss from the
Trisquel repository. The plugin in now shows up in Evolution under
plugins, but clicking on it does not toggle between enabled and disabled
like it does for other plugins. Why might this be, and how can I enable
this plugin?

Thanks!

Mason
