Thanks for submitting a bug report. The problem does indeed
occur in the Python normalization code:

>>> unicodedata.normalize('NFC', u'\u0B47\u0300\u0B3E')
u'\u0b4b\u0300'

I think the following line in unicodedata.c needs to be changed:

          if (comb1 && comb == comb1) {
              /* Character is blocked. */
              i1++;
              continue;
          }

to

          if (comb && (comb1 == 0 || comb == comb1)) {
              /* Character is blocked. */
              i1++;
              continue;
          }

Martin, what do you think ?
