These 2 Gtk-WARNINGS are due to some errors in the settings.ini file and gtk-widgets.css of the mac-os-lion theme.

To Correct them,

sudo gedit /usr/share/themes/mac-os-lion-theme-v2/gtk-3.0/settings.ini.

Use # for comments instead of * .. */

sudo gedit /usr/share/themes/mac-os-lion-theme-v2/gtk-3.0/gtk-widgets.css.

Goto line number 1971 and replace padding: 8; with padding: 8px;

That's it. No more warnings from Gtk. Have a Happy Time using mac-os-lion-theme !!!
