Change page type should not include primitive types like '/type/int'
Bug #292977 reported by Edward Betts on 2008-11-03
Steps to reproduce:
1. Edit a page
2. Select 'Change Page Type'
3. Type /type/int
4. While typing a drop down appears which includes /type/int
Primitive types like /type/int are not valid page types, they should not appear in the page type dropdown.
