Problem solved, thanks for the help, all. It was a combination of two
retain problems - first, the stray [wrapper release] down in
windowControllerDidLoadNib, and the second, accidentally releasing an
autoreleased object deeper into my methods.
All in all, just another lesson that memory management's of the utmost
importance in Cocoa.

I'm having troubles with some NSDocument code that I, a Cocoa newbie,
wrote. I'm trying to preserve an NSFileWrapper passed by
loadFileWrapperRepresentation:ofType: within the NSDocument. If I
create a new file, I can save it, even multiple times, and all's well
and good. However, when I load a file from disk and try to save it
again, my application crashes.
If I comment out my "wrapper = newWrapper" line in
loadFileWrapperRepresentation, the application runs and saves, albeit
without loading any of the data. This looks eerily like a simple
retain problem, but if it is, my newbie eye certainly can't find it.
I sliced the detailed pieces for loading and saving out of the
routines. What's left is enough to cause the crashing behavior when
saving files, which actually occurs after the loading/saving is
complete during the event loop, not anywhere that's easily >> debuggable.
