Hi Goran, The reason is (almost certainly) the fact that the two CRSs (coordinate reference system)s use a different Datum, which I suppose is the case, because in the Proj4 description you provide they have a different ellipsoid (The Bessel ellipsoid versus GRS80). Unfortunately, for the datum-transformation to be included when transforming from one CRS to another, you need to provide QGIS (actually the underlying Proj4 library) with details about that, and they seem to be missing. I cannot know which datum transformation is needed, maybe ask your Croatia mapping agency/Survey departement or Google for "datum transformation HR_GK_6 to HTRS96/TM"...
