 Yep, that the introduction of BooleanType or so ...

 Hm, what do You mean with "commiting to an url"? So far I cannot
produce any error and this stayed away "fixing" bugs the
BooleanValidator  I did not see ...

 I can reproduce this without problems :)

 Thanks for the patch! I have put in in the CVS (with a minor quirk,
so it still runs with python 2.1.3).
 Unit tests now pass with Zope2.6.1/python2.1.3 and Zope2.7-rc4/python2.3.2

 Please everybody test if this does not break something else ;-)

Cheers,
Clemens
