plugin build is broken

[Jonh Wendell <jwendell gnome org>]

Hello, folks.

It was reported that the plugin fails to build:
https://bugzilla.gnome.org/show_bug.cgi?id=599146

The attached patch (trivial) fixes the build in my machine, however I
would like to know why this fails now but built fine before.

Also, it was suggested to drop the plugin from the source [1]. What are
the plans?
