[z3-five] Error in Product - works under Five 1.31, not under 1.33 or 1.35

[kevin7kal]

I have a product/application that works well under Zope 2.91 with Five 
1.31 but not under Zope 2.92 with Five 1.33 or Five 1.35.

The product adds a menu item to the ZMI add drop down menu.  When I add 
a new object through the ZMI the object is added, I can enter a value in 
a field and click add and every thing works as expected.

Under Zope 2.92 with both Five 1.33 and 1.35 I recieve an error
Site Error
Resource Not Found
Sorry, the requested resource was not found
check the resource and try again
Resource: + GET

I thought that adding the line
<five:traversable class="OFS.Folder.Folder"/> to configure.zcml was the  
fix for this?
I also have
<five:traversable class="myModule.MyClass" />
There is no error event.log, this looks more like a 404 error. 

As always, all help is appreciated.
