Form Validator Running stripslashes incorrectly on raw POST results

[eluser]Treeda[/eluser]
I'm having exactly the same problem...

example comment form, set minimum ttext 10 to

submit bla\bla it will throw an error (correct) and i repop form but the raw post data is missing the \
but if form_validation runs successfully so lets say bla\bla\bla theslahes will be kept.

any offical fix or hint for this?
