I made it work despite the red wine - but now I don't remember what I changed 
to make it work :-D (kidding)

Today I wanted to change my other connections to the new-style syntax. I have 
a Plasma.Label[1] connected to a method in my class in "old-style" that works:

  QObject.connect(self.currency_from,
      SIGNAL("textChanged(const QString &)"),self.do_convert_from)

I tried to change it the way you showed but apparently it wasn't as simple as 
I was hoping:

 self.currency_from.connect(self.do_convert_from)

"self" is a subclass of plasmascript.Applet [2].

This resulted in the following exception:

Original exception was:
Traceback (most recent call last):
  File "/usr/share/kde4/apps/plasma_scriptengine_python/pyappletscript.py", 
line 55, in init
    self.pyapplet.init()
  File "/home/tol/snippets/currency-converter-plasma/contents/code/main.py", 
line 453, in init
    self.currency_from.connect(self.do_convert_from)
TypeError: argument 1 of QObject.connect() has an invalid type
