Error upgrade WooCommerce 2.0.1

Hello,

I just updated to 2.0.1 and I get this error : Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘woocommerce_price_filter_init’ was given in /homepages/36/d416291444/htdocs/FllOb/wp-includes/plugin.php on line 406

On store, I haven’t product images. ??

Sorry if my english is bad, I’m French.
