Product destroy layout

Hello.
I have some small problem. When I add some products they destroy a layout of category.

Normal:
http://gamersware.pl/index.php/myszki-dla-graczy.html

Broken:
http://gamersware.pl/index.php/simracing.html

I dont know why. I can add other products and it will be ok. I try several variations with no image no description ect.
Any idea?

Thx for help
