This was my problem when using umask: /usr/local/share/glib-2.0/schemas/gschemas.compiled didn't have the needed permissions.
I manually changed the permissions for the files shown as "Installing" and while "/usr/local/share/glib-2.0/schemas/cx.ring.RingGnome.gschema.xml" was shown, "gschemas.compiled" was not (or at least the path was not shown, but "Compiling GSettings schemas" was). I wonder if this may have been related to a previous report about contacts not being added/removed. However, this permissions issue was causing a segmentation fault while the other issue simply did nothing.
