[Zope] WebDav Bug?

Hi, Who do I report a webdav bug to?? Just in case you might want to know: PROBLEM: When connecting to Zope running on Redhat Linux 7.1 using any version of windows, the windows explorer creates a ghost folder of the parent folder in the current directory. This folder looks like a regular folder, but clicking on it causes an error. It always happens even on 2.4.3 of Zope. Is there a fix for this? Thanks, Luis.
