Bug Report Sharing Buttons

Given the recent news I thought I would turn off the Google+ button on my account and ran across a minor bug. With the Google+ turned OFF, and the Pinterest button turned ON, on the main image screen for an artwork all works well, but clicking through to the “framed print” page and using the buttons under the image there, the Google+ AND THE PINTEREST buttons cease to work if the Google+ switch is OFF.
Likely to be more relevant when Google+ does actually die.
