Chances are, in your "setter calls" you are trying to set something that cannot be directly set on $product. It could even be the "setTeinte" as I am not sure what that is trying to set. But as we cannot see all your code, it is a little difficult to say, so as I guide, take a look at the code below, which sets some information directly on the product and then stock levels. It does therefore, illustrate how certain data has to be set. I hope it helps.

$SKU = (string)$XMLproduct->Sku;
$product = Mage::getModel('catalog/product')->loadByAttribute('sku',$SKU);

if ($product) {
    //Product found, so we need to update it in Magento.

    $product->setName((string)$XMLproduct->Name);
    $product->setPrice((real)$XMLproduct->SalePrice);
    //$product->setDescription((string)$XMLproduct->LongDescription);
    //$product->setShortDescription((string)$XMLproduct->Description);

    $product->save();

    $productId = $product->getId();
    $stockItem =Mage::getModel('cataloginventory/stock_item')->loadByProduct($productId);
    $stockItemId = $stockItem->getId();

    $stockItem->setData('manage_stock', 1);
    $stockItem->setData('qty', (integer)$XMLproduct->QtyInStock);

    $stockItem->save();

    echo $SKU," Updated: Name: '",(string)$XMLproduct->Name,"', Price: ",(real)$XMLproduct->SalePrice,", Stock level: ",$XMLproduct->QtyInStock,PHP_EOL;

    $updated++;
}
