Chrome browser, unless the Marketplace category has sub-categories, it will only display one item per page.
For example, Nexus under the Marketplace has two pages but only displays a single item on each page. Firefox correctly displays ten on the first and the rest on the second. This affects gallery and downloads as well as they are the other Marketplace categories without sub categories.
3.3 related? Strange as hell... Confirmed on my desktop and laptop Chrome instances. Everything is fine on FireFox and IE 9 as far as I can tell.
Not sure if this is a IPB site bug or a Nexus bug or a 3.3 bug. Move as needed.
