Sorry, I didn't think to post it because it's not a generally useful patch. It eliminates rather than fixes the functionality.

Here's to hoping Woothemes gets this sorted out. As it stands, automatic updating to 5.3.11 is still broken, and instead of stating this directly, it claims that your currently installed (out of date) version is current.

That's a cute side effect of woo_get_fw_version returning the currently installed version # instead of throwing an error if http://www.woothemes.com/updates/functions-changelog.txt isn't available for download (which it isn't, at the moment.)
