Hey Matt, try the code below. It works reliably for me.
Make sure you've included:
http://oauth.googlecode.com/svn/code/javascript/oauth.js
http://oauth.googlecode.com/svn/code/javascript/sha1.js
script type=text/javascript
var requestUrl = 'http://...';
var ck = '...';
where the issue lives.

The Python OAuth library already includes the expected base string in the
error response. What API or library are you concerned about?
