[Zope] tacker error

I have the following error when trying to view a trackerWiki on Zope 2.3.3, i.e. the product adds ok, but when clicking on it to try and view it I get the error. The product is the latest CVS snapshot of tracker from http://www.zope.org//Members/klm/TrackerWiki/ Error Type: TypeError Error Value: __str__ returned non-string (type tuple) I have submited a bug report, but was wondering if someone had seen the same problem. thanks Mick
