Hi Florian,

here are a couple of hints on how to debug this problem on your own:

- make the simples use case of a menu, a menu entry and the usage of 
@@view_get_menu. And I mean the *simplest*. Your case is *not* the 
simplest. I'm talking about one brain-dead simple package, one 
configure.zcml and one very very dumb template. If you get that working, 
evolve from there and see where it breaks.

- start with everything being publicly available (zope.Public), then 
restrict on permissions and see where it breaks. Do the same with every 
other possible fanciness: start with the simplest thing and evolve.

- once it breaks and you know where it breaks, you'll want to find out 
why. Use a debugger like pdb to debug the @@view_get_menu view or other 
code step by step. If you've really found a bug in the Zope 3 source, 
file a bug report in the collector. Do not forget to also mention which 
branch of Zope 3 you're using. The above info suggests you're using an 
SVN install of a certain revision, but it doesn't say whether it's the 
X3.0 branch or the trunk.

Giving some patience and a good approach to debugging, you'll find the 
problem sooner or later. I'm sure it's just a very stupid little thing 
like a typo.

Good luck,

Philipp
