Notice: Undefined index: und in theme_views_view_galleria() (line 98 of /var/www/xxx/sites/all/modules/contrib/galleria/theme/theme.inc).

Warning: array_merge(): Argument #2 is not an array in theme_views_view_galleria() (line 99 of /var/www/xxx/sites/all/modules/contrib/galleria/theme/theme.inc).
