I have trouble with Magento 1.9.1 using the standard RWD,
I'm display products using the following code,
{{block type="catalog/product_list" column_count="6" products_count="12" name="home.catalog.product.list"alias="products_homepage" category_id="3"template="catalog/product/list.phtml"}}
It doesn't matter what I set the column count at it will always not display the correct number of products on each row and also adds in blank space instead, the missing products are then displayed on the next line down,
See example here,

Any idea what is going on here?
