1. emacs -Q
2. M-: (make-vtable :columns '("column") :objects '())
3. Observe an error like (wrong-number-of-arguments #<subr max> 0)

I ran into this when trying to display a list which can sometimes be
empty.  At the very least it would be nice for this to provide a better
error message.

I think this is a duplicate of bug#73775.
