Brian,

  this sounds suspiciously like the OS is letting you get away with
accessing an already-(auto)released object. Make sure you're
retaining your objects correctly.

  Most command-line apps only have one autorelease pool in their main
routine, while Cocoa apps get one from NSApp that is created and
released each time through the event loop.

  So, very likely, your objects are "pending for release" in the
command-line tool, while in the Cocoa app, they have already been
released. You're just "lucky" that your bug doesn't show up in the
command-line tool, while in Cocoa you actually *notice* that the
rug's been pulled from under your feet.

  Could that be your problem?
