[PyKDE] multiply-defined

[Frederick Polgardy Jr]

The problem is a linker error resulting from the fact that you are defining 
the same methods in more than one place -- generally this happens when 
something is defined in a header file that should be in a source (.cpp) 
file.

But it's impossible to say much more than that without seeing your code.
