I can reproduce the segfault, here's a backtrace:
(gdb) run

This is with menu-cache-1.0.0, and ~/.config/menus doesn't exist.
Also the mentioned /etc/xdg/menus/applications-kmenuedit.menu doesn't exist.
Apart from the segfault I don't see an issue with the lxqt menus, only under
LXDE
there seem to be no menu entries.
Dumb question: How is lxmenu-data related? Is that also required for LXDE?
