Is it possible either you need to retain the return value from this
method, or you're over-releasing it? Have you tried turning
NSZombieEnabled on?
You mentioned not being familiar with release and autorelease.
(Actually you said you couldn't find details on when to use them,
which I find surprising.) Have you read the document Jonathan del
Strother recommended?

Do not try to guess your way around retain and release -- you'll just
be wasting a lot of your own time. It's not that hard once you get
the hang of it.
