dpkg-maintscript-helper should handle missing files gracefuly, also it
does not print that kind of error on a missing file either. But in any
case I don't see what would lead to that conclusion.

The failing version here is 2.004.1-3 which is just the one preceding
the switch away from defoma (in 2.004.1-3.1) and as such of the new
usage of dpkg-maintscript-helper, so that's another hint that this
cannot be it. My guess would be that another program called from the
maintscript (defome itself most probably) is failing, so a problem
that should probably be handled by a new fixed lmodern on upgrade.
