ND OCW About the Professor Image Bug :: ReferenceException: None not referenceable

[tom]

This appears to be a very small corner case that was caught on the Notre Dame site, and we don't know how to reproduce it. So this traceback is just for our records. It happened with an About the Professor image and somehow resulted in a null image. The only fix was to copy all the HTML into another page object and delete the offending About the Prof object. Here is the text of the traceback (can't seem to attach a screen shot atm):

From Cathy at ND:

I know that the course builder was used initially, because I did that part. But, what the production assistant did beyond that, I have no idea. But, if you look at the history for the page, it looks like the image never did load correctly.
