No, I say the same. The font definition in your file contains
Mapping=velthuis-sanskrit which means that you use TECkit mapping.
This map works in several steps. first it converts all characters from
transliteration to Devanagari (k to क, .n to ण etc). In the second
step the vowels are properly set (dependent+independent). In the third
step conjuncts are formed by replacing consonant+consonant by
consonant+virama+consonant and the fourth step adds virama if the word
ends in a consonant. The last step removes the inherent short "a". If
you type विकर्णनीय in Devanagari, the following sequence of characters
will be seen on the input:
व ि क र ् ण न ी य
The first two steps will do nothing. The third step will see क
followed by र and will insert virama. The fourth step will see a
consonant at the end of the word and thus add a virama. The resulting
sequence of characters will thus be:
व ि क ् र ् ण न ी य ्
this is the very reason why half-kra will be formed because it exists
but conjunct kr.n does not exist. You can see other errors if you
specify Mapping=velthuis-sanskrit and input the text in Devanagari.
Trust me, I am the author of this map.

Oh, I forgot that the repository contains just the sources, you have
to run make which means that fontforge is needed too. I can share the
fonts from my computer.
To Steve: isn't it a good time for another release? The problem is
that the latest release does not work with XeTeX in TeX Live 2013 at
all but the latest svn revision works.
