Comment 4 for bug 1445745

I resolved or worked around the issue after reading a comment on a Red Hat bug page: https://bugzilla.redhat.com/show_bug.cgi?id=1164449#c4 It appears that the Glade utility uses an "n_rows" property field on GtkGrids that is no longer good and the UI for the Software Center has a line that has that defunct property in it.

Commenting out line 409 in /usr/share/software-center/ui/gtk3/submit_review.ui so that it looks like:

<!-- <property name="n_rows">4</property> -->

allowed me to then submit a review to software in the Software Center, with no discernible defects or errors.
