I try.
First you have to go to the file:
src\zope\app\schemacontent\browser\__init__.py

and change the line 80 and 81 form:

getPerm = getattr(self, name+'_get_perm_widget').getData()
setPerm = getattr(self, name+'_set_perm_widget').getData()

to:

getPerm = getattr(self, name+'_get_perm_widget').getInputValue()
setPerm = getattr(self, name+'_set_perm_widget').getInputValue()

The method getData() is wrong, but I'm not shure if
getInputValue() is the right method.

What I did for to run into the Bug,

- Delete the data.sf

- Start Zope3

- Loggend in as Manager

- Go to Utilities
  http://localhost:8080/++etc++site/default/Utilities/@@utilities.html

- Click "Add utility"

- Add a util "Content Component Definition"
  with the id "ccd"

- In the following form I filled out the fields
  Register as: ccd
  The permission needed to use the component: zope.View
  Registration status: Active
  The other fileds I let unchanged.

- Klick Add

- Then you get on the form for to add the schema

- Add buddydemo.interfaces.IBuddy
  as a usefull schema. it's in the second half fron down.
  (should be sorted by name) :-(

- Click change

So, the content component definition is added.

- Go to the tab "Define Permission" on the 
  content component definition called "ccd"

- Set a Accessor and Mutator permission on the 
  field First name, say zope.View

- Now you can do what you whant, I was adding a folder in the root
  called folder.

- Then you go back to the Utilities and see the "Define Permission"
  content component definition called "ccd", the permission of 
  the First name are still there.

- Now stop and start the Zope Server.

- Go back to the content component definition called "ccd"

- Go to the "Define Permission" and you see the permission
  of First name are gone. I get just (no value) on the
  First name Accessor and Mutator permission.

  But the permission are set to zope.View.
  I could not find out why the permissions are not show
  correctly and just available till you restart Zope.
  
I guess the Choice widget with a "Permission" vocabulary
can't render values and loose their not persistent data. 
(but its useing a persistentDict() for to store them.
Perhaps I did a fault in changing getData() to getInputValue()? 
But getData() is wrong. (What's the right method?)
The permission itself is set correct, it's just a problem of 
rendering the value. 

My Zope3 Server is running on Win XP.
