I went all in and fiddled everywhere... :) I got the hint to update  
configure.zcml by looking at how the grok admin interface was  
registered, but I realised that it was probably the wrong way.

I defined the permission 'my.perm' in app.py of the protoncms package.  
The error shows up during startup when I add a  
grok.requires('my.perm') to a view in the protoncms package, claiming  
that I haven't defined the permission. I have double and tripple  
checked the spelling. And the code did work prior to refactoring.
