I think I understand now what's going wrong. AFAICS BaseRequest.py needs 
to be fixed.

@Dieter: Could you please have a look at this diff and tell me if it
- looks reasonable
- resolves the infinite loop problem you had in a different context

I believe 'method' has to be reset to the default default method after 
copying the modified default method to 'entry_name'.

@Andy: Could you please check if this change in Plone's browserDefault 
script fixes your problem? (I know it's just a workaround, but CMF would 
need a terrible hack.)

Of course feedback from other people is as always welcome.
