Sur un formulaire avec code de suivi, en mode anonyme, mais pas sur la première page. Je n'ai pas réssui à reproduire, mais on a eu des traces de ce genre:

Donc on a un KeyError lors de l'affichage du code suivi, au niveau de wcs/forms/root.py

    def tracking_code_box(self, data, magictoken):
        '''Create the tracking code box, it displays the current tracking code
           if enabled, and a 'remove draft' button if the current form is a draft
           that has been recalled.'''
        r = TemplateIO(html=True)
        if self.formdef.enable_tracking_codes:
            r += htmltext('<div class="tracking-code-part">')
            r += htmltext('<h3>%s</h3>') % _('Tracking code')

            tracking_code = None
            draft_formdata_id = data.get('draft_formdata_id')
            if draft_formdata_id:
                formdata = self.formdef.data_class().get(draft_formdata_id)         <----- ici, KeyError
                tracking_code = formdata.tracking_code
            else:
                tracking_code = data.get('future_tracking_code')

le self.formdef.data_class().get(draft_formdata_id) ne semble pas exister.

Ce qui n'a pas vraiment de sens pour moi (ça me semble impossible).
