Developer comments (common to all duplicates if any)

Can be sometimes reproduced under Windows (but not always, 4.5.3). Under Linux (4.6.2), it is certainly impossible to have this bug because the browser looses focus and setData is called when the message box is displayed. Under Linux: when commenting confirm message box, crash reproduced (not always but often). ModeItem::_curve is not null because ModeItem::setData() is called by modes->setEnabled( b ); in void ModalCurveBrowser::on_curveScroll_valueChanged( int v ) before resetting curve pointer in ModeItem. Fix: change order, call setEnabled after everything in ModalCurveBrowser::on_curveScroll_valueChanged( int v ), available in all release >20100525
