That will need further examination in bugzilla and in something else than
GNOME Shell for comparison. You may be right that it is the bug you've
linked, but then you could ask yourself why you don't run the program
as your normal user.

That one says mode 644 which is _not_ executable, but only rw for user
and readable for anyone else.

That one is _older_ than what Fedora 20 ships: 0.18.0

That's because you've not downloaded all packages you need.
Either you point Yum at package repositories to solve such dependencies,
or download all needed packages yourself and install them _at once_ with
either Yum or RPM.

You're missing the "dconf" package of the same version. This is just
dconf-editor.
