HTTPS Everywhere 2.2.1 breaks Google Toolbar Search predictions

With version 2.2.1 of HTTPS Everywhere installed the old Google toolbar (7.1.20110512W) loses the ability to display search predictions. Normally, as each new character is entered into the toolbar search field, a dropdown list of appropriate search predictions is displayed. With this version of HTTPS everywhere, nothing. I have noticed that each character entry causes a message in the error console which states "HTTPS Everywhere: TypeError: sink.asyncOnChannelRedirect is not a function"

Disabling HTTPS Everywhere restores the search prediction functionality to the Google toolbar.
