For what it's worth, on checking the latest audacious-plugin source from upstream, <http://distfiles.audacious-media-player.org/audacious-plugins-3.7.1.tar.bz2> it looks like they fixed this differently. I see both sid and stretch only have 3.6.2-based packages, but it looks to have already been fixed in the same manner as 3.7.1 in that version.
