Selecting portrait orientation in proyect summary (Xcode) causes crash in cocos2d-2.1beta3-x-2.1.0

Hi, I have just installed cocos2d-2.1beta3-x-2.1.0 and creating a box2d proyect I have change the supported interface orientation to only “portrait” and the default proyect created by the template crash at start. I`m receaving a SIGABRT on line

@
int retVal = UIApplicationMain(argc, argv, nil, @“AppController”);

at main.m

Is this a bug?

Thanks in advance
