Another thing I missed, Bryse: in comment #15, you explain that you where not able to crash X by visiting the site. It is because the crash happen on the result page. So you need to reverse-lookup a French number, which are ten digits long. Usually, after searching for 10~15 numbers, X crashes.
Which makes me think: perhaps we should contact the webmaster of the offending site.
