Mail Mime extension PEAR

Bonjour,

J'ai un problème avec le code suivant, et comme je suis nul en POO,
vos lumières me seraient de grand secours.
Ce code utilise les extensions mime de PEAR.

J'obtient une erreur :
*Fatal error*: Call to a member function on a non-object in
*mailmime.php* on line *62

*Et je n'ai aucune idée de la cause. Ce que j'ai lu dans les FAQ ne m'a
pas aidé.

Merci de votre aide,

Julien*
*
