busted nautilus build

[Luis Villa <louie ximian com>]

Notice this in my jhbuild this morning:

make[2]: Entering directory `/home/louie/cvs/nautilus/po'
file=./`echo ar | sed 's,.*/,,'`.gmo \
  && rm -f $file && /usr/bin/msgfmt -o $file ar.po
ar.po:7234: duplicate message definition
ar.po:4023: ...this is the location of the first definition
/usr/bin/msgfmt: found 1 fatal error
make[2]: *** [ar.gmo] Error 1

Can someone fixificate, please?

thanks-
Luis
