Having both "DCHECK(webView)" and "if (!webView) return false" are contradicting
with each other. Should we clean this up? 

     return false;
 
   // If the user has selected text in the currently focused frame we print
   // only that frame (this makes print selection work for multiple frames).

+  WebKit::WebFrame* focusedFrame = webView->focusedFrame();
+  *frame = focusedFrame->hasSelection() ? focusedFrame : webView->mainFrame();
   return true;
