Those who wish to use the new git version of Gnome-shell from Ricotz Testing PPA, note that packages gnome-shell, gjs and pango are built against new glib2.0, which must also be installed (libglib2.0 >= 2.31.0~) from this PPA.
I have all these installed and I can tell you they do work very well.
But at least Eog will not work with libglib2.0-0_2.31.0
