I've made the change required to ignore the empty string named cgi 
values in my interchange install previously.

However the point remains that any interchange users expecting the 
auto-return feaure from paypal to be handled, will be sorely 
dissapointed, as I was to receive paypal payments and no completed 
orders. And obviously the customers seeing 500 errors, and not being 
sure that their order has been completed is not good either.

I think this is something paypal has changed to recently, as I have many 
completed orders from paypal, which were completed by interchange as well.
