It appears there was a dependency change from KDE 3.2.3 to KDE 3.3.0, where 
the latter required kutils and the former didn't, and that only affected 
khtml_part.sip. Because of the way I hacked around that (so that both 
versions would be supported), the end result is that khtml_part.sip is stuck 
at KDE 3.3.0, which it should be. 

There shouldn't be any problem providing the documentSource method.

I'll get to that in the next release (which is already hopelessly late).
