I'll have to look at how Phil handled the typing for PyQt4/QStringList because 
that's where I stole the code from. Apparently I didn't steal quite enough. 
If you got that far, PyQt4 compiled correctly.

It should show up in a couple of other places as well, unless KUrl::List is 
still older code and I copied newer code for the other instances.

My pleasure.

Thanks for the early bug report!
