I found a translation bug with contact form

Hi there,

I think I found a bug with the contact form, I just tested it on a new installation of drupal to be sure and it works (the bug lol).

Si I explain :

After the installation of drupal, I activate locale module and import french translation (because I'm french). In addition I activate the contact module.

My aim is to have a contact module in french and in english, depend of the language selection in the member profile.

So, by default the translation of additionnal information works

In english : You can let us a message using the contact form below
In french : Vous pouvez nous laisser un message en utilisant le formulaire ci-dessous

If I change the additionnal information field in "site building > contact form > settings" by putting "this is a test" for example, the translation of this field don't work anymore.

Drupal will show "this is a test" in both language.

The strange thing is, if I return to locale module, I search the original sentence : "You can let us a message using the contact form below", it is here ! with his translation : "Vous pouvez nous laisser un message en utilisant le formulaire ci-dessous". But this translation dont apply anymore....

It's a strange behave and I dont find how to fix it.

In addition, drupal seems to not allow the translation of contact category, how can I fix this ?

thanks
