When installing the actual Version of YihawDirectory (http://www.zope.org/Members/Roug/Yihaw) by importing it into a 2.2.2 Zope, I got the following traceback. This happens both with and without the current hotfixes. Importing it into 2.2.1 equipped with the current hotfixes works without flaws. Any ideas what's going on here? I don't want to go back to 2.2.1 :-/ <snip> Zope has encountered an error while publishing this resource.
