Disable the copy option after making an empty selection in okular

What to do: If text selection is activated and someone right clicks the mouse button after making an empty selection the copy text option still appears which logically should not. Actually, when this kind of copy is made, as it is an empty selection with no texts, the previously copied text are actually the copy content.
The student is needed to study on some part of the code and then he has to correct the problem. So, the desired output will be to show no copy option where it is inappropriate to show.
You are probably need to hack into ui/pageview.cpp. To download the code go to: http://okular.kde.org/download.php.
Expected results: No copy option should appear after empty selection.
Prerequisites: Some Qt Knowledge.
