[bt-devel] crash upon right-click -> Strong's search

Gary, can you help with this? In CBibleReadWindow::updatePopupMenu() 
there's code "m_actions.findStrongs->setEnabled( 
displayWidget()->getCurrentNodeInfo()[CDisplay::Lemma] != QString::null 
);" and I think it doesn't work anymore after changing to WebKit/JS. The 
same goes for CLexiconReadWindow, and there's code in CReadWindow using 
getCurrentNodeInfo()[CDisplay::Lemma], too.
