Depends in which country. Think about it, the input filter network with 
a ground prog will have caps which will charge abruptly when connecting. 
If the ground prong enters first, the next pin to touch produces 
unbalanced current in the circuit to charge the caps on its side. This 
may trip a GFI. I don't think that a longer ground prong would help (a 
shorter one might but it may be dangerous).
