Hallo all,

I'm just starring at this in my gdb console and I have no idea how this is possible. What kind of thing can cause this?

Where's the problem. We have _requests NSMutableDictionary, which does contain one key / value pair. If I send valueForKey: message with existing key, it correctly returns pointer to a valid object.

If I send valueForKey: message with non existing key, it returns nil except one key - http://assets0.fusionads.net/automatic_2.jpg. It returns 0xffffffff pointer even if this key does not exists in _requests dictionary.


Don't use valueForKey - use objectForKey.

The former invokes various KVC related logic to the key (which, amongst other things, will attempt to translate "a.b" as a multiple part key path).
