Has anyone noticed that the images from https://ci.inria.fr/pharo-contribution/job/Pier3Addons/PHARO=30,VERSION=stable,VM=vm/ are having issues with the editor?  When one tries to open it, it gives the loading message in the text area, a few inactive links, and the message

  MessageNotUnderstood: receiver of "builder" is nil

I'm getting this from a Pharo 3 VM and testing the files from Mar-7th until today's image.  At first I thought this may be due to WARenderCanvas being undefined, but I've found an image from a month ago that works fine.  Anyone know the last time this worked successfully?
