Not sure, but a reasonable guess is at least 1998, the "gentoo" GTK+ file manager. I still have the conversation (from 2000) with Daniel Robbins, founder of the Gentoo Linux distribution, where we discussed the name collision. There was no issue, we just both agreed to peacefully co-exist. :) Very cool, since I learned that he, like me, came from an Amiga background. Although he out-cooled me by a laaarge margin, having worked at semi-legendary game company Psygnosis.
