Comment 15 for bug 1704533

OTOH, doing so makes the source package actually name the files libgweather.mo. Maybe a better way, to not confuse Rosetta, is to change line 87 in

https://git.gnome.org/browse/libgweather/tree/libgweather/gweather-weather.c

from

    bindtextdomain (GETTEXT_PACKAGE, GNOMELOCALEDIR);

to

    bindtextdomain ("libgweather", GNOMELOCALEDIR);

But that's untested.
