[Zope] Zope 2.7 Problem w/Value Error: unpack list of wrong size

Absolutely true in the long term. In the short term, three people 
(including me) stumbled on this issue and must deal with it in the short 
term.

I don't think that anyone uses ZClasses for new jobs. Old sites 
unfortunately use them. Rewrite them to products may be expensive 
time-wise. How can I charge my clients for a rewrite that brings no new 
funtions? That's not a rhetorical question. Please tell me and I start 
removing ZClasses from an old project and charging my customer for it.
