Could you get gdb backtrace from this? Although depending on your  
configuration it might be tricky to get core dumps.. http://dovecot.org/bugreport.html 
  has some ideas, but it doesn't really talk about deliver. I guess  
the main things are:

  - user should have a writable home directory (where the core is  
written to)
  - run ulimit -c unlimited before running your MTA
