'manage_permission' (really, the methods it calls) make the assumption (unwarranted in your case) that they are called on an acquisition-wrapped object. In your case, the root object is *not* wrapped, and therefore does not have the 'aq_acquire' method. Normally, when called via the publisher, the root object *is* wrapped (in a RequestContainer).

A workaround would be to wrap the root first:

zopectl> debug
Starting debugger (the name "app" is bound to the top-level Zope object)
>>> app
<Application instance at 40dc1bf0>
>>> app.aq_chain # not wrapped
Traceback (most recent call last):
File "<stdin>", line 1, in ?
AttributeError: aq_chain
>>> app.manage_addFolder( 'testfolder' )
>>> tf = app.testfolder
>>> pr = tf.getPhysicalRoot()
>>> pr.aq_acquire
Traceback (most recent call last):
File "<stdin>", line 1, in ?
AttributeError: aq_acquire
>>> pr = pr.__of__(tf)
>>> pr.aq_chain
[<Application instance at 40dc1bf0>, <Folder instance at 40e51d10>, <Application instance at 40dc1bf0>]
>>> pr.aq_acquire
<CMethod object at 0x40dfac60>
>>> manage_permission("View", ["Owner"])

The real fix would be to rip out the use *anywhere* of 'self.aq_acquire'; the 'aq_aquire' function from Acquisition will always do the Right Thing (TM) if the object is not yet wrapped (the difference parallels using 'aq_base', 'aq_parent', 'aq_inner' as functions rather than methods).
