It depends on what your initialization does.

Conceptually, there are 2 types of initialization routines:

System-wide initialization, which happens once when Ethereal starts.
Per-file initialization, which happens when a new file is loaded.

The state-keeping routines need to keep state per-file, so they are
initialized when a file is loaded. (Both SMB and NCP have this type
of routine).

ethereal_proto_init() (in gtk/main.c) calls the system-wide
initialization routines, proto_init(), init_dissect_udp(), and
dfilter_init().
