This is indicative of over releasing an object. Likely some objects in
all of the code you didn't post is taking an object you don't "own"
and releasing it. Then later this object is also release by the auto
release pool.
Review the memory management docs and look at using NSZombie and/or
use Instruments to track down the object and code path involved.
