New gettext in Rawhide causing builda failures?

[Richard Hughes]

I'm trying to build a new upstream release of gscan2pdf -- but a lot
of other upstream software also looks affected, this is the build
failure:

/usr/bin/perl -MExtUtils::Command -e 'mkpath' --
/builddir/build/BUILDROOT/gscan2pdf-1.2.5-1.fc21.noarch/usr/share/locale/ab/LC_MESSAGES
msgfmt -c po/gscan2pdf-ab.po -o
/builddir/build/BUILDROOT/gscan2pdf-1.2.5-1.fc21.noarch/usr/share/locale/ab/LC_MESSAGES/gscan2pdf.mo
po/gscan2pdf-ab.po:7: header field 'Last-Translator' still has the
initial default value
po/gscan2pdf-ab.po:7: warning: header field 'Language' missing in header
msgfmt: found 2 fatal errors

This builds fine in F20. I think a newer gettext may be being more
strict about Last-Translator and Language -- any ideas or best
practices on how to fix it? Patching 33 .po files in a spec file seems
like the Wrong Way (tm).

Thanks,

Richard.
