emacs -r -Q -l em-ls -l esh-cmd -eval "(customize-set-variable 'eshell-ls-use-in-dired t)"

M-: (dired source-directory "-lg") RET
;; Signal eshell-interactive-output-p: (wrong-type-argument arrayp nil)

It fails because eshell-current-handles is nil.
Even if this variable is set, then (throw 'eshell-external ...
in `eshell--do-opts' won't be catched.

The following works:
M-x eshell RET
ls -lg (eval source-directory) RET
