[TYPO3-commerce] pagebrowser problem

[Cray Flatline]

I'm setting up two different sites with commerce 0.9.2 and both of them 
have same problem: it shows pagebrowser with correct number of pages, 
but if I go to Page 2 - it shows nothing. No even one product item in 
the list. and such thing on the any page exept first. Does anybody know 
such problem? and what I need to do with it?

I tried completely turn off real_url - doesn't help at all
