PVST behaviour on 3550 running 12.1(12c)EA1

Is it normal for a port configured as an access port to respond to PVST multicasts recieved on this port. Surely this behavior should be reserved for Trunk ports?

This is normal behavior. Spanning tree BPDUs, including PVST BPDUs, are sent as multicast packets - and they are also sent on access ports (since it is perfectly feasible to connect two switches using access ports).
