I got and "internal server error or misconfiguration" (or words to that effect)
page when I submitted this bug. This prompted me to hit the Submit button again,
causing the dupe #176215. It apparently also caused all the bug content except
the title to be lost. I'm not too keen to enter all data again, so here's a
brief summary instead:
You need to add the following line to the bottom of the %prep section in
gimp-print.spec:
perl -pi -e 's,^(msgstr) "Ingl.s",$1 "Spanish",' po/es.po
Let me know if you need additional information.

Thanks.  I have fixed this for the next release of Red Hat Enterprise Linux, as
well as for Fedora Core 5.
