The description of the problem is a bit mysterious. I'm not sure this is the answer but...

If you use the decocker to bring down the hammer you will find that the trigger is locked back. If with your thumb you then pull the hammer back, you will find that it can be pulled all the way back and will never catch (because the decocker is engaged. If you were to let the hammer go at this point it would travel with full force and strike the block that is just barely holding it back from the pin. Could it be that this force could (1 out of 100000 times) create enough of a shock to jar the pin and discharge the weapon?

If on the other hand you use the decocker to bring the hammer down, and then take it off safe to release the trigger forward, and then return it to safe...you will notice that the hammer cannot be pulled back and thus exerts much less force on the firing pin block if released from essentially a half-cock position.

I am just offering a guess here...not even sure it's a good guess.
