Causes error saving Genesis SEO Options

This plugin seems to cause an error with the Genesis theme framework version 1.9 where the plugin stops the ability to use the in-built genesis SEO options from saving.

With the plugin enabled, if I try to update an SEO description in the post and save it, the post updates fine, but the genesis SEO description field remains unchanged.

With the plugin disabled everything seems to work fine.
