I've uploaded a -2 revision of the packaging at http://mentors.debian.net/debian/pool/contrib/g/gmameui
The dsc can be grabbed at:
http://mentors.debian.net/debian/pool/contrib/g/gmameui/gmameui_0.2.10-2.dsc
It now installs a compliant .desktop file, the debian/copyright file is compliant with latest revision, and the few remaining 80+ character lines have been split. It's mostly to keep track with the Ubuntu Karmic package changes.
I'd appreciate if it could get reviewed and, if ok, sponsored into Debian unstable.
