emacs -Q

`M-x load-library dired-x'

`C-x d' for a dir that has a subdir

With cursor on a subdir line, `i', to insert its listing.

With cursor on the inserted-subdir heading line: `!'.

You get that raw error message.

`!' is not intended for directory heading lines.  But the error
raised shouldn't be one you see.

Yes, I've tried this in 26.3, and the error you've described is there.
However, in master, this bug has been fixed.

I haven't tried it in Emacs 27 yet, but if it's not fixed there yet,
it's likely too late to fix it now.
