is this a bug of pagination?

I’m a bit stuck now.
see also http://ellislab.com/forums/viewthread/181979/

controller/index/ pagination works perfectly
site: muzica.infosite.ro/evenimente.html

controller/function/variable/ (records are poulated corectly but pagination links remaining at the first link ).
site: muzica.infosite.ro/evenimente/categorie/lansari_de_carte.html

the only compromise solution is to make num_links more big then pages
something like $config [‘num_links’] = ‘100’;

Does anyone know what else I could do?
