Same here,

spearfish60:

nviz -q
Panel -> Vector points
New
bugsites
File -> Save State
filename
<ok>
segfault.


It happens in panel_site.c, proc Nviz_site_save (line 176), 
on this call:
	# useatt
	puts $file_hook "[Nsite$i get_att useatt]"

which takes us to get_att() in src/map_obj.c line 1516.

then in
    case SITE:{
        case SV_ATT_USEATT:

it tries  atoi(argv[3]) but there is no 4th arguement to convert:

 argc=3
  argv[0]=[Nsite21720]
  argv[1]=[get_att]
  argv[2]=[useatt]
  argv[3]=[(null)]


The atoi() is trying to fetch the attribute number for this:
int site_attr_get(Tcl_Interp *interp, geosite * gp, int nattr)
{
        char buf[1024];

        sprintf(buf, "%d", gp->use_attr[nattr]);

        Tcl_AppendElement(interp, buf);
        return(TCL_OK);
}


If I change argv[3] to argv[2] it gets rid of the segfault, but I don't
know if that is the intended logic.
