Or you can just subclass KHTMLPart and create a method to handle clicks.
Something along these lines:

class HTMLPart(KHTMLPart):

    def __init__(self, parent):
    
        KHTMLPart.__init__(self, parent)

        # Other initialisation code goes here.

    def urlSelected(self, url, button, state, target, args):
    
        if button == QMouseEvent.LeftButton:
        
            # Construct a new URL.
            new_url = self.make_url(url)
            
            # Inform the parent object of the new URL so that it can
            # add it to the history trail.
            self.parent.add_next_url(new_url.url(0, 0))
            
            # Open the URL.
            self.openURL(new_url)
    
    def make_url(self, url):
    
        # Is the URL absolute or relative?
        if KURL.isRelativeURL(url):
        
            # A relative URL
            
            # Join the current URL and the new URL.
            new_url = KURL(KURL(self.url()), url)
        
        else:
        
            # Create a KURL object to use to open the new URL.
            new_url = KURL(url)
        
        return new_url

    # Other methods go here.
