This is related to the "playground" package (it's not a plugin problem), since the BMP plugin from upstream doesn't work either, and I get several signal-related errors from the main applet which are related to main breakage in the "playground" package.
Upstream is currently broken, though, from my experience with the current DARCS repository yesterday. Both "playground" and "playground-plugin-xmms" should be removed unless someone recovers upstream development.
