Comment 15 for bug 176566

I had the same error message with Products.Collage. I had to debug someone's implementation of a collage viewlet that couldn't find a perfectly findable provider. I got the <UnauthorizedBinding context>. Weird.

In the end, I only had to change the zcml security declaration on the viewlet from "zope2.View" to "zope.public". So this matches a bit with the "zope2 security check" comment of the original bug report.

Hope this helps someone :-)
