There is an error in the code that processes cross domain links. An extra " is being added to the end of the onclick code.
On line 367 in class-frontend.php:
$trackBit = '_gaq.push([\'_link\', \'' . $matches . '//' . $matches . '\']); return false;"';
$trackBit is closed with a "
However, later on line 394, a second " is added after $trackBit.
As far as I know this only affects cross domain. I think in other cases $trackBit is left open until line 394. It seems to work properly if I remove the " from line 367 after return false;
