Silverlight 2 : XamlParseException

Bonjour,

J'ai encore un petit problème, quand je veux afficher un contrôle custom, je reçois une exception de type XamlParseException (ligne:0 colonne:0).
Celle-ci ne se produit que pour un contrôle mais je n'arrive pas à trouver l'origine de celui-ci et ce même en utilisant le debugger.

Voici le xaml du composant :
