I'm curious re the purpose of the narrow unpainted strip on the leading edge of the vertical stabilizer on some (but not all) LH A320-family aircraft. You can see what I mean on the A321 below. It starts about 3 feet above the fuselage and goes almost all the way to the top.

Quoting tdscanuck (Reply 5): I'm not aware of any large airliner with deiced empennage.
Not quite sure what your criterion for "large" is, but I know that the EMB-145 series and the DC-8, DC-9 and MD-80 all have tail de-ice systems. I can't speak for the others, but on the MD-80 it is activated manually from the cockpit by diverting bleed air from the wings to the tail for a short period of time. The wings and empennage cannot be de-iced simultaneously. Prior to landing, the crew typically cycles the tail de-ice one last time during descent to make sure the empennage is uncontaminated.
I am not aware of any A320 series aircraft with tail de-icing or anti-icing capabilities. As tdscanuck mentioned, the strip in the photo is likely to be an HF antenna.
EDIT: Judging by this diagram I dredged up, it may not be an antenna. A reinforced leading edge like others have mentioned sounds like the most likely option.

Quoting HAWK21M (Reply 8): The Aerodynamic airflow will prevent ice buildup.
Is it that, or is it more that ice accretion on the vertical stabilizer isn't that critical? I would tend to think it is the latter, as aerodynamic flow doesn't prevent ice buildup on wings, hence the reason we have boots and/or heated leading edges
