[Zope] REQUEST.items() problem

Hi, i'm trying to show all data contained by REQUEST, but when i write the next code, the computer overloads and Zope doesn't response: <dtml-in "REQUEST.items()" sort> <dtml-var sequence-key>:<dtml-var sequence-item><BR> </dtml-in> If i use REQUEST.form.items() or REQUEST.cookies.items(), it works perfectly, but there is data in 'Other' that i need. Am i doing something wrong or is a problem of Zope? I'm using Zope 2.3.3, python 1.5.2 and Debian/woody. Thanks. Bye.
