Add-on script stopped worked with 20170306 Nighty

I hope I am posting in the correct forum since this issue crosses operating system platforms.

Beginning with the Leia Nightly, Version 20170306, the script.image.resouce.select add-on has stopped working. I get the same error on Windows 10 and on Linux Ubuntu 16.04. I have tried it with different skins but the problem remains. Based on this I am assuming that the problem lies within Kodi and not the skin or the add-on. In addition, if I revert back to the nightly of 20170305 the problem goes away.

Below is the snippet from the kodi.log that shows the error:
