SuSE 9.3 - Gnumeric with strange error

Hi, I like to use Gnumeric when do simple calculations. But in SuSE 9.3 in default installation Gnumeric acts strange. When I input integer number like 10 or 12 it does calculation. If I input 1,2 or 10,23 numbers in calculations it refuses stating that this is "Invalid expression". If I input in cell 1,2 or any non integer number it rounds it down to integer, i.e., 1,2->1,00 , 2,8->2,00 etc.

From where I can get normally working Gnumeric?

My locale is Lithuanian, but I do not think that it is problem... Audrius
