I have posted this as part of the Web Video bug report, but this fault also happens when you try and move pages on both the Music & Film 'News & Reviews' sections. I presume it's to do with an EOF situation, but what's more confusing is that the Music bit shows 5 pages and the Film has 3, all of which are redundant.
EDIT: The message is triggered when you click on any number, even page 1.
Any chance of a job, btw? :o)
EDIT 2: This message no longer appears and pagebuttons work correctly.
