Cocos2d : Adding sprites in an array causes application to Terminate with uncaught exception

Question

Hi, I'm getting an uncaught exception error when I try to add sprites to an array, and everything looks fine to me.. I'm using MonocleStudios Simplegame project for this monoclestudios dot com/static/simplegame.zip

Code should be fairly self-explanatory:

[code]

@implementation GameScene

• (id) init { self = [super init]; if (self != nil) {

  Sprite * bg = [Sprite spriteWithFile:@"game.png"];
  [bg setPosition:ccp(240, 60)];
  [self addChild:bg z:0];
  [self addChild:[GameLayer node] z:1];
  Sprite * bg1 = [Sprite spriteWithFile:@"game.png"];
  [bg1 setPosition:ccp(211, 260)];
  [self addChild:bg1 z:0];
  //the above works fine!
  Sprite * bgX[50];
      //if comment out the next 3 lines, everything runs but I get an "unused variable" warning
  bgX[0] = [Sprite spriteWithFile:@"mytree.png"];
  [bgX[0] setPosition:ccp(240,150)];
  [self addChild:bgX[0] z:0];  
  }
  return self;
  

  }

@end

The following works fine (Cocos2D 0.7.3, if that matters with 2.1 SDK):

Sprite *sprites[SPRITE_COUNT];
for(int i = 0; i < SPRITE_COUNT; i++) {
    sprites[i] = [Sprite spriteWithFile:@"file.png"];
    [sprites[i] setPosition: ccp(0, 0)];
    [self addChild: sprites[i] z:0];
}
