I already try with print_r !

it shows the content "array(['name'] => 'name test')" in #description and #value, but never on #default_value

The name field is varchar(50), with 'name test'.  Just it.

Yesterday a PHP expert was here, he take a look at this, we try a lot of possibilities, no clue whatsoever

It cant be explained :)

Imho, that behaviour suggests that something is wrong with $row['name'] and 
less with Form API itself. (Because string concatenation fails even before 
the Form API gets the value passed over.)

Not sure, but maybe print_r($row) and/or gettype($row['name']) reveals some 
useful information...
