[Zope] Zope 2.7.2 with Ape 1.0 installed in root, fails to restart, without any usefull logging, after adding a local role

[Tim Connor]

Thanks, Shane.  That fixes the problem of Zope not starting, and better 
than the other syntax I tried, but it still doesn't fix the core 
problem.  My root Ape installs have issues with adding a local role, as 
then the default roles get axed.  If you add this fix then Zope re-adds 
Owner (and Authenticated, as you need to duplicate the fix a couple 
lines lower) during the start-up, but not Manager - and they are not 
really added, but sort of hacked in by the start-up code.  Shouldn't Ape 
be somehow dealing with this exact situation anyways, or is there just 
something wrong with my installs?

Thanks again for the help,
Tim
