Strange issue when compiling for device

For some strange reason, my app compiles fine when I try to run it on simulator, yet strangely when I try to run it on my iPod touch, I get the following error when compiling:

Code:

Internal error occurred while creating dependency graph: *** -[NSCFArray initWithObjects:count:]: attempt to insert nil object at objects[27]

Could this be a provisioning issue or maybe a bug in the sdk? I'm currently using sdk 3.1.2 (gonna update soon!).

 

ok thanks! (Sorry for the late reply!)
