I got this crash report from a remote user, but I cannot find any useful tip to resolve this issue, may be it\'s a retain problem but I cannot understand why because of I\'m usi
Looks like an object was deallocated yet the code assumed it was valid. Have you tried running "Zombies" in Instruments? It will tell you where you sent a message to an invalid object. If you're using that with Emulator, be sure to do Hardware->Send Memory Warning frequently as you try to reproduce.
