Comment 3 Rahul Bhalerao 2008-02-10 16:20:30 UTC 
The first two and last combinations are rendered wrong due to incorrect ligature rules defined in the font. Correct fonts that use 'post-base form' feature for these two conjuncts (post base forms of Ya and Va) render properly on pango. This also includes fonts developed for windows tested on pango.
Comment 4 Rahul Bhalerao 2008-02-10 16:28:30 UTC 
The combination 3 and 4 are similar issues and a related bug is already filed at:
http://bugzilla.gnome.org/show_bug.cgi?id=447035

I think this bug should closed.
