He's saying that 'make' crashed because of this translation. It can
be found in the make/de.po file of GNU make 4.1 and newer.

The workflow with PO files is designed in such a way that even if
translators make a mistake like this (providing a translation with %s
for a string that doesn't contain %s), "msgfmt -c" will catch it.
BUT "msgfmt -c" makes this check only for a message marked with
'#, c-format':

  de.po:272: number of format specifications in 'msgid' and 'msgstr' does not 
match
  msgfmt: found 1 fatal error

The question thus is: Why was this message not marked with '#, c-format'
in the make.pot file? The answer is: because it is an argument to the
macro DB (defined in debug.h), and xgettext doesn't know that DB behaves
like printf.

Compare the results of
  $ xgettext -o - --keyword=_ --keyword=N_ file.c
and
  $ xgettext -o - --keyword=_ --keyword=N_ --flag=DB:2:c-format file.c

So, the problem will be fixed if you add the option
  --flag=DB:2:c-format
to the variable XGETTEXT_OPTIONS in the file po/Makevars.
