Upgraded to the cvs development version, but getting same error.
It happens when I click the 'next-page' widget for more results, not
on loading the page.
I've only been able to reproduce this bug on the SSL version of the
duckduckgo page. I don't get it using https://encrypted.google.com --
but that page renders the 'next results' as a regular link, not a
widget (if that makes a difference).
