[vbox-dev] getStatistic method issues

[Igor Shkodyrev]

But does the getStatistic method work for python bindings at all?
I already spent a bunch of time trying to get this method working for
all kinds of hosts/guests combinations (Ubuntu/WinXP as host +
Ubuntu/WinXP as guest) and couldn't succeed in it, i get the mentioned
errors.
