Could you have a look at this case again?

The messages to deliver have the smtp "mail from" and Return-Path
set to <>. (they're bounces) 

I can reproduce the problem by telnet'ing to the postfix server, and
sending bounce mails to an account over quota.

It seems that deliver is sending bounces on the bounces, which I
think is an error.
