No idea what is happening there, but I see that m_xPopupMenu in
include/svtools/popupmenucontrollerbase.hxx is a VCLXPopupMenu and it
seems to only need to be a VCLXMenu in case it makes any difference to
use
m_xPopupMenu = dynamic_cast<VCLXMenu*>(xPopupMenu.get());
instead of
m_xPopupMenu = dynamic_cast<VCLXPopupMenu*>(xPopupMenu.get());
in PopupMenuControllerBase::setPopupMenu
