[Zope] Migrating to Zope 2.10.1 breaks unrestrictedTraverse

[Ian McCracken]

I'm trying to get an object by walking a path. Previously, I used 
baseobject.unrestrictedTraverse(path).  Upon migrating to 2.10.1, 
though, doing the same thing often produces the following error:

  File "/usr/local/zenoss/Products/ZenModel/Organizer.py", line 148, in getOrganizer

    return self.getDmdRoot(self.dmdRootName).unrestrictedTraverse(path) 

  File "usr/local/zenoss/lib/python/OFS/Traversable.py", line 259, in unrestrictedTraverse

AttributeError: REQUEST


The problem appears to be that the Traversable mixin assumes that 
self.REQUEST will be available; since we're calling it from outside 
Zope, though, there is no request.  Any thoughts? Why was this changed, 
and is there an extant way to get the same result without just writing a 
simple method that walks the path?

Thanks,
Ian McCracken
