Notice : Undefined index: name dans system_requirements()

hello
i got this error in the upgrade from drupal 6to drupal 7

Notice : Undefined index: name dans system_requirements() (ligne 34 dans /home/vetosent/www/modules/system/system.install).
the code is
$profile = drupal_get_profile();
if ($profile != 'standard') {
$info = system_get_info('module', $profile);
$requirements['install_profile'] = array(
'title' => $t('Install profile'),
'value' => $t('%profile_name (%profile-%version)', array(
[LINE 34=>] '%profile_name' => $info['name'],
'%profile' => $profile,
'%version' => $info['version']

what change can i do ?
