Yeah, my momma taught me long ago ;)

No problem, it was just curiosity.

I think it was false alarm. I used a lambda expression as slot and must have 
misunderstood why the other lambdas in the same function can use '[&]' without 
ending up with invalid references in the body. I only need the watcher instance, 
so I'm just passing the reference to it explicitly. No more crashing and less 
ambiguous anyway :)
