Problems with Network.destroy

So in my game my character has a self-destruct feature. With this code:

 if(networkView.isMine){
             if(Input.GetKeyDown (KeyCode.Mouse0)){
                 GameObject instantiatedProjectile = (GameObject)Network.Instantiate(sefDestruct, transform.position, transform.rotation,0);
                 instantiatedProjectile.GetComponent<Detonator>().Explode();
                 Network.Destroy(this.gameObject);
             }
         } 

my character doesn't dissapear on fire. But if I comment out the two lines spawning the explosion then he does.

 //GameObject instantiatedProjectile = (GameObject)Network.Instantiate(sefDestruct, transform.position, transform.rotation,0);
 //instantiatedProjectile.GetComponent<Detonator>().Explode();

What gives?
