piuparts probably didn't test frog* if their dependencies failed,
otherwise it would have found the same error there

I'll take a look

If needed, I can sponsor that as well

use debian/$package.maintscript instead of doing it directly in maintscripts

put in there lines like

    rm_conffile /etc/ucto/tokconfig-es 0.4-1~

no dpkg-maintscript-helper prefix, no default arguments, no trailing
comments!
use $VERSION_TO_BE_UPLOADED + "~" as prior-version argument

this will generate appropriate pre/post/inst/rm scripts with the same
content
