I'm a bit confused. Yes, Emacs23 shows the same error with pop-up-frames
to 't'. However, if I explicitly set it to 'nil' for Emacs24, I still
get the same error:

--> emacs --batch -Q --eval "(setq pop-up-frames nil)" foo bar baz
Unknown terminal type

If the issue is really just the changed default for `pop-up-frames', I'd
say the default should be again changed to 'graphic-only instead of
'unset.
