The gtk code in the deb is not the latest (but that's what I expected, it being a few posts up), and I don't know if it is supposed to install a launcher in the gnome menu, because it doesn't, it is a strange error,
when I before the deb tried the install.sh a menu entry was put there, the first time, but not again after I uninstalled and reinstalled.
It's not a killall gnome-panel or log out/in problem, since I've tried those, but I don't know if it is a sysres bug or perhaps a gnome bug.
As for the maturity of my own code, I think it is ready for upstream, if you can confirm that the post 472 bug is fixed and no new has appeared.
EDIT, I need to update the changelog... I always forget that!
