[jQuery] Selector *= not works in Safari 3.2.1 and Chrome 1.0.154.43

Hi all,
Here is my situation.
HTML Page DTD Type is declared as following
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/
TR/xhtml11/DTD/xhtml11.dtd">
Javascript Code as following
$("#fp > option[text*='"+subject+"']").remove();
Where #fp is a <select>...</select> object
Works fine in IE7 and FireFox 3.0.5
How can I fix this line or is a bug?
Thanks in advance!
