On the other hand this could be still a bug in VirtualBox or in FreeDOS. Which version of FreeDOS did you install, did this guest work with older versions of VirtualBox and is the problem reproducible?

This is a triple fault.
SS:SP = 1fe0:0001
A normal computer would also triple fault under such condition. I guess that raising the triple fault is intended to reboot the (virtual) computer. Try
(user manual section 8.8.1) to tell the VMM that it should reboot the VM if the guest raises a triple fault.
You will probably ask why this setting is not enabled by default. The reason is that there are several ways to reset the computer (e.g. by using the ACPI), and triggering a triple fault is kind of a sledge hammer and normally not used. But for DOS the sledgehammer is probably the intended mean ...
