Undefined index value in _multiselect_build_widget_code()

On line 244-261 in multiselect module the if clauses are checking for is_array($value['value']). In my case, using taxonomies, the 'value' index is never set so the error log fills up with "Undefined index" notices quite quickly.

 if (is_array($value['value']) && array_key_exists('value', $value['value'])) { // Field collections have them nested.
        $selected_options[$value['value']['value']] = $value['value']['value'];
      }
      elseif (is_array($value['value']) && array_key_exists('tid', $value['value'])) { // Field collections have them nested. Taxonomy
        $selected_options[$value['value']['tid']] = $value['value']['tid'];
      }
      elseif (is_array($value['value']) && array_key_exists('nid', $value['value'])) { // Field collections have them nested. Node ref
        $selected_options[$value['value']['nid']] = $value['value']['nid'];
      }
      elseif (is_array($value['value']) && array_key_exists('uid', $value['value'])) { // Field collections have them nested. User ref
        $selected_options[$value['value']['uid']] = $value['value']['uid'];
      }

I propose wrapping these if cases together like this:

if(!empty($value['value']) && is_array($value['value'])){
        if (array_key_exists('value', $value['value'])) { // Field collections have them nested.
          $selected_options[$value['value']['value']] = $value['value']['value'];
        }
        elseif (array_key_exists('tid', $value['value'])) { // Field collections have them nested. Taxonomy
          $selected_options[$value['value']['tid']] = $value['value']['tid'];
        }
        elseif (array_key_exists('nid', $value['value'])) { // Field collections have them nested. Node ref
          $selected_options[$value['value']['nid']] = $value['value']['nid'];
        }
        elseif (array_key_exists('uid', $value['value'])) { // Field collections have them nested. User ref
          $selected_options[$value['value']['uid']] = $value['value']['uid'];
        }
      }
