Doesn't really mean much to me... Actually, it means a lot!

The error is in "manage_tabs". It's almost surely caused by a name clash for the name "URL". "manage_tabs" expects "URL" to be the URL from REQUEST. Apparently, someone was able to create either an attribute or an instance named URL. This object is acquired and therefore takes precedence over the REQUEST's URL. Obviously, the new object named URL does not support "__getslice__". The problem will go away, when you edit "App/dtml/manage_tabs.dtml" and replace all occurrences of "URL" by "REQUEST.URL". This is a bug. Please file a bug report to <http://collector.zope.org> Dieter
