i finally managed to stich this panorama. the reason why image was so 
big was that hugin for some reason left a very big empty space below all 
images - the problem also mentioned on this list several times.

usually i can significantly reduce that space by changing horizontal 
control point pairs, but this time i was not able to do so.

anyway, after cropping it in gimp to the furthest edges it was reduced 
to 31184x3615

so ability to crop output (probably in preview window ?) would help in 
cases when resulting images are too large because of empty space added.
