Just tried it:

TypeError: PyKDE4.solid.Notifier cannot be instantiated or sub-classed

But I also just tried "new-style" signal/slots:

Solid.Networking.Notifier.statusChanged.connect(self.netstate_changed)

Which gave:

Traceback (most recent call last):
  File "/usr/share/kde4/apps/plasma_scriptengine_python/pyappletscript.py", 
line 75, in init
    self.pyapplet.init()
  File "/home/tol/google-translator/google-translator/contents/code/main.py", 
line 55, in init
    self.setup_network()
  File "/home/tol/google-translator/google-translator/contents/code/main.py", 
line 301, in setup_network
    Solid.Networking.Notifier.statusChanged.connect(self.netstate_changed)
AttributeError: 'builtin_function_or_method' object has no attribute 'connect'

Which could indicate that statusChanged hasn't been implemented as a signal in 
PyKDE? Or am I totally on the wrong track here?
