:-(. It's a pity that the release team didn't let 0.98.3 in really -
then this would all have been much clearer much earlier. Such is life
I guess ( and I can understand where they were coming from).

It isn't just me - google reveals:

It is possible that it is leftover from upgrading etch to lenny, then
tracking lenny.

Having said this, it isn't a priority as it is just a warning, and
doesn't seem to affect lenny.
