jQuery 1.x does not load properly in CHROME mode starting at version 1.8.0:
org.openqa.selenium.WebDriverException: com.gargoylesoftware.htmlunit.ScriptException: TypeError: Cannot find function attachEvent in object [object HTMLDocument]. (http://code.jquery.com/jquery-1.8.0.js#864)
The last working version appears to be 1.7.2.
Unit test is attached (based off test from #1493, thanks to Barry Pitman)
Fixed in SVN, thanks for the test.
Actually the reason was node/window.addEventListener() and removeEventListener() :)
