[Zope-CMF] KeyError: main_template when upgrading to CMF 1.3.2

[Tim Terlegård]

I get an error after upgrading to CMF 1.3.2:

Error Type: KeyError
Error Value: main_template

I don't get any tracebacks in debug mode. In debug mode I get
the following when Zope starts:
"ZODB Could not import class 'URLTool' from module 'Products.CMFCore.URLTool'"
I have no idea if these errors are related.

I tried to see what caused the error and it seems to be CMFCore.
When I have my old CMFCore and the new CMFDefault, CMFCalendar and CMFTopic
it works fine. The URLTool message also disappears. But if I then add the
new CMFCore, I get both these errors.

On top of this I have Plone. The error seems to me to belong the CMF,
so I try this list first.

Any clues?
