Comment 2 for bug 618907

One more issue.

I think the dependencies should be corrected too.

Now this gnome-shell_2.31.5-2ubuntu1 depends on too old gobject-introspection.
(gir1.0-glib-2.0_0.6.15~git20100713, libgirepostory1.0-1_0.6.3).
The dependency should be on the version 0.93-0ubuntu4 of gobject-introspection.
The new gnome-shell will not work with the old gobject-introspection.

And by the way threre is no such a file as libgirepository1.0-1_0.6.3, the first libgirepository1.0-1 was the version 0.9.3-0ubuntu2.
Before that, the package name was libgirepository1.0-0.
