The new function Selenium.prototype.doWaitForCondition fails when the test raises an exception in the beginning. I often have tests that may raise exceptions until the state changes. While it might be possible to rewrite my tests, I think the proper solution is to ignore exceptions.

So I changed the currentTest.waitForCondition function as follows:

currentTest.waitForCondition = function () {
        try {
            return eval(script);
        } catch (e) {
            return false;
        }
    };
