I read the GNOME bug report more closely and came up with this plan. Thoughts?

1. Fix the issues/shortcomings with the patch for GNOME bug 731173 and
get it accepted into the latest GNOME, even if that version is of
GNOME is 3.15/3.16 rather than 3.13/3.14.
2. Backport the patch to GNOME 3.12.
3. File a bug report for Debian to accept the backported patch.
4. Ping mitya57 on #debian-devel
