Can you introduce KSnapshotSendToActions::waitForFinished, and call that function instead? Will block if not yet finished: but that's okay. It's unlikely that the user will click that fast.
main.cpp

Don't do this. Rather create 'window' on the stack.
I'd really like to get this into master (finally!)
Could you fix those issues?
