Lines should be stored as a tuple since they should be immutable.  All other Zope properties are stored as such (__ac_permissions__, manage_options...), but for some reason, these were not.  The result is as follows.

obj.lines.remove('value') works and can possibly be persisted if anything else (proxied method, etc) causes a _p_change on that object.  Note that this is possible even though the user is not allowed to 'Manage properties'.  

(as a sidenote, I could never understand why lines are initialized to [''] instead of [])
