This is the regular behavior of Emacs Info-index when called interactively
from a buffer with an attached file.  It simply doesn't support what you
are trying to do.  As mentioned in another response to your issue, use the
action type link-to-Info-index-item instead.

The above works a bit better now but again you should choose the action
type link-to-Info-node instead.

Hope that helps.  We'll be closing this issue now.
