Notice: Array to string conversion in token_replace() (line 110 of D:\Install\XAMPP\xampp\htdocs\wsc\includes\token.inc)

The message appears when the module is enabled (Tested with core 7.16).
After putting some tracing, the problem happen in the token_replace function in token.inc on calling
str_replace($tokens, $values, $text).

Example:
$text =[user:url]
$tokens = Array ( [0] => [user:url] )

When the module is NOT enabled:
$values = Array ([0] => http://localhost/wsc/en/user/5414 )

When the module is enabled:
$values = Array ([0] => Array
(
[0] => http://localhost/wsc/en/user/5414
[1] => http://localhost/wsc/en/user/5414
)
)
