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

[Paul Howell]

Where is this in the Collector, Chris?  I'm having trouble finding it.  I'm 
still getting bit by this one (2.7.0 from earlier this month) with some 
older products using ZClasses... perhaps the fix never quite made it in to 
the released Zope?  Meanwhile, I'll dive in and look for Dieter's almost 
surely easy to fix solution myself.  Sort of like the old textbook saw, 
"The solution is left as an exercise for the reader."
