It may be that theDict is getting auto-released, since
dictionaryWithCapacity, and other initializers like it, return an
auto-released object. This is more fully covered in Apple's Cocoa
documentation, but the general gist is that unless you call alloc on
the class, then use an object method to initialize it, the return
value will be auto-released.
The other side of this is that if you do retain theDict, either
through alloc or by calling retain, you need to either call release or
autorelease on it.
If you're working a lot with Cocoa, you should join the cocoa-dev
list. Also read the document on Cocoa memory management, it'll be very
helpful.
