Custom labels bug in 1.1.2

Hi Folks!
There is one bug in v.1.1.2 with custom labels.
It is resolvable:
* go to classes/helper.php
* find function wpml_translate
* replace it with the code below:


public static function wpml_translate($taxonomy_info, $string = '')
{
if (empty($string))
{
$string = $taxonomy_info->label;
}
//***
$check_for_custom_label = false;
if (class_exists('SitePress'))
{
$lang = ICL_LANGUAGE_CODE;
$woof_settings = get_option('woof_settings');
if (isset($woof_settings['wpml_tax_labels']) AND ! empty($woof_settings['wpml_tax_labels']))
{
$translations = $woof_settings['wpml_tax_labels'];
//$translations = unserialize($translations);
/*
$translations = array(
'es' => array(
'Locations' => 'Ubicaciones',
'Size' => 'Tamaño'
),
'de' => array(
'Locations' => 'Lage',
'Size' => 'Größe'
),
);
*/

if (isset($translations[$lang]))
{
if (isset($translations[$lang][$string]))
{
$string = $translations[$lang][$string];
} else
{
$check_for_custom_label = TRUE;
}
} else
{
$check_for_custom_label = TRUE;
}
} else
{
$check_for_custom_label = TRUE;
}
} else
{
$check_for_custom_label = TRUE;
}

//+++
if (empty($string))
{
$check_for_custom_label = FALSE;
}
//+++

if ($check_for_custom_label)
{
global $WOOF;
if (isset($WOOF->settings['custom_tax_label'][$taxonomy_info->name]) AND ! empty($WOOF->settings['custom_tax_label'][$taxonomy_info->name]))
{
$string = $WOOF->settings['custom_tax_label'][$taxonomy_info->name];
}
}

return $string;
}
