https://qa-reports.gentoo.org/output/genrdeps/rindex/dev-util/gdbus-codegen as pointed out by mgorny tells that most or all versions/revisions of audacious-plugins are RDEPENDing on gdbus-codegen. It is highly unlikely that it is needed at runtime, as gdbus-codegen is a build time tool to generate D-Bus code from an dbus interface description during the build process. Please review and adjust to only DEPEND if indeed appropriate, as is likely (unless it actually doesn't use the tool at all during build time - that might be from release tarballs if the code is pregenerated into tarball, and autoreconf alike stuff doesn't get ran).
