I took the trouble to upgrade our site from Zope-2.1.2 to 
Zope-2.1.4, but alas, no dice! There is another bug in 
Zope-2.1.0 that makes it impossible to create multiple selections
at all, and produces the same error output. 

Any suggestions?

P.S. I'm not too comfortable running a beta version at this moment.
