======
IOP_generate_profiles detects obj->orb is NULL, so nautilus aborts.
I also use gdb to watch value change of obj->orb:
** (nautilus:3652): WARNING **: FIXME: Need to shutdown linc connections ...
Hardware watchpoint 4: ((struct CORBA_Object_type *) 0x82378b0)->orb
Old value = (struct CORBA_ORB_type *) 0x8235908
New value = (struct CORBA_ORB_type *) 0x0

It seems someone shutdown orb, and the next access cause nautilus abort.
BTW, running gedit/totem will also abort with message: "ERROR:iop-profiles.c:606:IOP_generate_profiles: assertion failed: (obj && (obj->profile_list == NULL) && obj->orb)".
What cause this happened? Any idea?
