Warning: asort() expects parameter 1 to be array, null given in _charts_settings() [#935432]

I copied the example verbatim from here http://drupal.org/node/233916
$example = array(
'#type' => 'pie3D', // Display a 3D pie chart
'#color' => 'f0f0f0', // Background color, in RRGGBB format
'#title' => t('Example'), // Chart title
array(
array('#value' => 60, '#label' => t('60%')),
array('#value' => 25, '#label' => t('25%')),
array('#value' => 10, '#label' => t('10%')),
array('#value' => 5, '#label' => t('5%')),
),
);
return charts_chart($example);

and i get these errors

Same issue here,

I am not able to even visit the configuration page due to theses 'warnings', let alone create a chart

Running PHP 5.3.1

Update:
Turning on one of the sub-modules e.g. google charts solved this problem. I still think there is a bug here, perhaps implementing the hook on module enable to tell the user that they need to enable a sub module. Definitely the configuration page needs to be able to cope with 0 sub modules turned on and display a friendly message
