With some debuging added (same results w/ or w/o a src page set as SRC). 
Debug output is a continues fragment:
   khtml (part): KHTMLPart::frames frame1false
   khtml (part): KHTMLPart::frames frame2false
   khtml (part): KHTMLPart::frames 2
here KHTMLPart::frames return 2 frames, name and bPreloaded appended of
childframes. This frame has no name (=top frame)

   khtml (part): frame1KHTMLPart::frames 0 frame1
   khtml (part): frame2KHTMLPart::frames 0 frame2
here two time 0 for frame1 resp. frame2

   konqueror:        - viewName=   frame names:frame1,frame2
   khtml (part): KHTMLPart::findFrameParent: this =  URL =
      http://localhost/~koos/frameset.html findFrameParent( frame1 )
   khtml (part): KHTMLPart::checkFrameAccess: Unknown part/domain (nil)
      tries to access part 0x82fde10
So here konqueror asks top frame (after 'this = ' I added the frame
name) with a NULL as callingpart. And that makes
KHTMLPart::checkFrameAccess fail. 

Below the bt just before the call to KHTMLPart::checkFrameAccess. So I guess
its the frame access checks failing here. Can anyone check it with the 
3.3 branch, this was backported, no?
