On command line this works for me (Mandriva):
g.proj -c proj4="+proj=krovak +a=6377397.155 +rf=299.1528128 +dx=653 +dy=-212 +dz=449 +no_defs +towgs84=570.8,85.7,462.8,4.998,1.587,5.261,3.56" location=test Location test created!
Can you please try this as well? We have to understand if it is a g.proj problem or a GUI problem.
