It's a bug - fixed in tonight's snapshot.

There might be an underlying Qt bug as well as the problem is that 
QObject::sender() is returning a 0 pointer. It only happens the first time 
the script is run for a particular IP address - so DNS caching is obviously 
having an effect on the Qt behaviour.
