Hi,
After some manual tracings, I see that the Segmentation fault happen in
http://opengrok.libreoffice.org/xref/writer/sw/inc/viewsh.hxx#423

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
inline const SwViewOption *GetViewOptions() const { return pOpt; }
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I don't know how to fix this. Any hint, please?
After adding new radio button to print dialog as above, do I have to 
modify somewhere to get it work?

Thanks,
Ta Tung
