Conflict between pageroute and filefield

Hello everyone,

I'm encountering problems with pageroute when i try to upload a picture throught the filefield component. When i upload the content, i've got this error message :

une erreur HTTP 0 s'est produite. 
/site/lue/filefield/ahah/profile/field_profile_photo/0

When i try to upload the picture out of the pageroute it works fine.

I've found this fix that does not work in that case : http://drupal.org/node/239727#comment-802671

Thanks for you help.
