Conboy 0.6.2 is meant to be the next stable release. It basically the last conboy-unstable, but renamed. It's currently on it's way to extras-testing, so you probably still got it from extras-devel.
Please try to completely uninstall all versions of conboy or conboy-unstable and reinstall it. Let me know if that brings your icon back.

Ah and it should be optified now. And the same version is also available for Chinook and Diablo.
