Narrative:

Landed on runway 5 at buf, turned off at taxiway 'C' and turned down taxiway 'J.' as I approached the hold line for runway 32 I realized that I was not sure if I had been cleared across runway 32 or not. I started applying the brakes and by the time I had stopped I crossed the hold line for runway 32 with the front part of the aircraft. An aircraft that was a mi or so out was told to go around by the tower. Part of the reason that I missed the hold short call was that I was doing my after clearing the runway stuff while the first officer was talking on the radio. I was not concentrating on the radio like I should have.
