Konqueror cannot use math captcha

I know there is a serious bug in captcha that is currently being worked on -- I don't know if this is related to it or not. I do know that I have been able to use captcha successfully on my site using Internet Explorer, Firefox and Opera, but that when I try to use any node/login with a math captcha on it in a Konqueror browser, it always fails. This seems a different problem from the error message that displays reporting that the math problem was answered incorrectly because that message also appears in the browsers that work.
