I don't know.

It must be noted that I uploaded gettext 0.21 for unstable recently
and it propagated to testing today. Apparently the new gettext is more
nitpicky than the old one.

My feeling is that somehow you are calling xgettext "implicitly", i.e.
without being really aware that you are in fact calling xgettext.

If required I can ask gettext upstream about this, but we would need a
minimal test case and a little bit more of investigation on our side.

Thanks.
