Duplicate Title in RSS Feed

Hi Scott,

It appears Decode is producing RSS feed title duplication. We thought maybe it was our problem due to a plugin conflict, but we checked out the feed for your blog (http://beyondtheco.de/feed/) and it’s duplicated there too along with all the feeds listed in the Decode support topics and of course ours: http://bob.bluelotusworks.com and http://suzanne.bluelotusworks.com

To help, the references we could find to correct this are:

• http://codex.wordpress.org/Customizing_Feeds
• http://wordpress.org/support/topic/site-title-appears-twice-in-feed-how-can-i-change-it-so-it-displays-only-once?replies=12

Note the second thread properly discourages modifying WordPress core and references a fix at row 168 of functions.php in Twenty-Twelve 1.1.1 (the fix is at about row 200 in the current version of Twenty-Twelve.
