Have a look at collective.autopermission it solves these kinds of issues
and means you don't need to worry about using setDefaultRoles ==
'simpler' (the KISS principle :)

You'll need to include it in your eggs 'install_requires=' line and also
do an <include package="collective.autopermission" /> at the top of your
configure.zcml.
