I fixed a similar issue with 'structure' some days ago for Zope 2:

<http://svn.zope.org/Zope/trunk/lib/python/Products/PageTemplates/Expressions.py?rev=78767&r1=71802&r2=78767>

Not sure if both issues are related and if they should be addressed
on the Zope 3 level directly instead within the Zope 2 wrapper.
