2.6 Category paging not working

Hi

I have 2.6 on Apache with a custom structure of “/reviews/%post_id%” and category paging is not working but tag paging does work. First category page works fine, but 404’s after that. There is no custom structure for the tags and categorys.

I’ve seen some old posts on this sort of bug on older versions but looks like it was cured in 2.5. Has anyone found this bug on 2.6?

Thanks
