Hi Ludwig:

I took a look it seems the major change is to _generic.help.html.

at the top of that file I see this inside tal:define:

  qs request/env/QUERY_STRING;
  qs python:'&'.join([a for a in qs.split('&') if not 
a.startswith('@template=')]);

I assume the first qs is incorrect? I think the last definition is the 
one that's used.

I hope to have some more time to look at it this weekend.

Thanks for your suggestion.
