Reviewers dropdown in Crucible Reviews spins forever in IE8 - cannot add reviewers

When typing into the Add Reviewers box, or clicking the drop-down when Editing the details of a Crucible review, the box sits there and spins. This only occurs in IE8 (both normal and compatibility modes). It works fine in Firefox and Chrome.

The javascript error is:

which appears to be failing on

parsed.push(parser(r));

because

parser = eval('(' + resp.parser + ')');

is not successfully creating a parser. resp.parser appears to contain a function function (user){var participant = ...

And for some reason IE8 doesn't seem to handle creating a function using a string in an eval statement. Some web research mentions that IE8 doesnt seem to handle creating functions from strings very well, and you should instead use the "Function" method.
