Bug in use of <jahia_multivalue[...]>

I've got a problem in use of the getMultivalues() function that generate the <jahia_multivalue[...]> string.

The editors can create some keywords like "Mot-clé de test" in a dedicated container. I read this container to generate a Vector that contains the keywords. And the vector is use afterward to populate the values of some other fields.

When the editors create new keywords, they're encoded correctly (ie: Mot-Cl&eacute; de test"). They can select this keyword in the edit engine and validate it. But when the editors want to modify there choice after that, they can't because the value of the options in select are malformed :
<select class="input" name="listSelection_2729" onChange="handleListSelectionChange(document.mainForm.listSelection_2729,document.mainForm.elements['_2729']);">
  <option value="Mot cl&amp;eacute; de test">Mot&nbsp;cl&eacute; de test</option>
  <option value="Autre exemple sans accent">Autre exemple sans accent</option></select>
Is it a know bug ?
I use Jahia 4.0.6 with PostgreSQL 7.4.7.000 on Solaris 2.8.The DB is UTF-8 encoded.
