I recently took a look at this program (I was going to try packaging it, but since you're already doing it, I'll save myself the work ;) I've noticed that the icons don't contain an author's credit, but the software's about box says they come from the Dropline Neu! icon theme. I took the time to look up that theme's author, and his name is Silvestre Herrera (silvestre.herrera@gmail.com) So, please make sure you add that to your package's copyright file.
