views_rss doesn't generate correct language tag

The RSS generated will not validate for me because it doesn't print a language code.

views_rss.module, line 167:
attempts to print $locale, which is a global, and therefore needs a global $locale; line inserted somewhere before it, assuming this is the correct way to access globals, and not through a function or something. It doesn't seem to be gettable by variable_get the way the site name and mission are.
