If you insulate the interior wall, you should drywall & paint both sides & install a vapor retarder (kraft paper) to the warm side. This will limit vapor migration inside the wall, which will go from warm to cold.
Interesting. I've never heard of kraft paper as a vapour barrier - only poly. Must be regional differences. I agree that un-covered insulation is a bad idea. I would only insulate interior walls for sound.

Kraft paper is considered a "Vapor Retarder". Poly is pretty well impermeable, but kraft paper is designed to slow, but not stop vapor migration. Benefit being that, theoretically, water inside the wall structure could eventually dry through the retarder.

Selection or exclusion of vapor barriers and/or retarders is pretty important. The building science website that Nik333 linked to is a good source, but there are many other sources with great info. Depending on interpretation, though, some of them seem to contradict each other - newer seeming to supersede older, IMO.
