How can I create useful backtraces for libxfce4menu of xfdesktop? They 
tend to crash every time an item is added to the menu...


I recompiled them with --enable-debug=full, but I get these '??'s in the 
backtrace...


DBG[desktop-menu.c:301] _generate_menu(): menu file name is 
/etc/xdg/menus/xfce-applications.menu
DBG[desktop-menu.c:301] _generate_menu(): menu file name is
