You can ignore this mail, if you want.

Rustom,

Here is the context -

> Sorry I dont get the context.
> On my emacs 23.3.1 I can activate devanagari-aiba input method.
> Is there something else you want me to check?

Are you activating the input method like this - 

1. C-x C-m l Devanagari
2. C-\

Do you see a crash like this -

Debugger entered--Lisp error: (error "Can't activate input method `dev-aiba'")
  signal(error ("Can't activate input method `dev-aiba'"))
  error("Can't activate input method `%s'" "dev-aiba")
  activate-input-method("dev-aiba")
  toggle-input-method(nil 1)
  call-interactively(toggle-input-method nil nil)

> I dont know this input method (and google does not help) 

See [1]. They apparently has something to do with diacritic marks
(whatever that means).

See [2].  The table that compares two methods and is attached here for
future reference.  There are 12 entries in that table where the aiba and
itrans input methods differ.

I was wondering, as someone who is more familiar with Devanagari which
of these would you prefer as the input method.  If you think that you
have no particular opinion, I think we can leave the defaults as such.

Here is an entry for SHA.
