When I comment out nflog_unbind_group(ui->nful_gh) in  stop() inside 
input/packet/ulogd_inppkt_NFLOG.c,  ulogd does not segfault anymore.

Here I have question:

Does  *pi in
static int stop(struct ulogd_pluginstance *pi)

represent the NFLOG plugin or the individual log2:NFLOG ? I am asking 
because it get started only once with pluginstance_started(), and 
therefore should be stopped once (?)

Cheers,
