I think you already fixed this, but anyway, there are good chances that gnome-panel is asking for a 24x24 icon for 24 pixels panel. And if it doesn't, it will for a 25px or 26px panel.
I discussed with lapo about this, and he's right that adding padding in the panel should be okay. I have to try this. -- Panel always chooses 16x16 icon for KDE apps https://launchpad.net/bugs/34774 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
