Personally, I wouldn't want to get into doing C++ for signal/slot handling or 
connect in this case.  I should be able to make this work from the PyKDE 
side, but I didn't have much luck on the first try.

I assume you want a long term PyKDE fix, not just something to work on your 
personal system. Looking at the previous post, it seems I had a fix at one 
time, but there's a question of maintainability over future releases too, 
depending on how a fix is implemented. I'd like to avoid something I have to 
remember to add each release - I'd prefer something that happens more or less 
automatically.

I'd like to wait and see if Phil jumps in this thread. In the meantime I'll 
give it another look, and email Phil if he doesn't show up here.
