Usually extra releases of array-held objects come when the program
releases the object independently of releasing the array, which itself
releases the held objects. The autorelease which is causing the error
is probably coming from the array object.
I would take a break from coding and meditate on the design of the
program. It's unlikely you are encountering a framework bug, so I
suggest that a good high-level consideration will reveal your problem
more successfully than chasing through lines of code.
