The problem is in
visualization/nviz/src/map_obj.c

line 833 etc read like this (G_debug() I have added for me only):
    /* Parse mode returned for shade style and surface style */
    G_debug(0,"mode: %d",mode);
    if (mode & DM_GOURAUD)
    strcpy(shade, "gouraud");
    else if (mode & DM_FLAT)
    strcpy(shade, "flat");
    else {
    Tcl_SetResult(interp,
              "Internal Error: unknown shade style returned in
get_drawmode",
              TCL_VOLATILE);
    return (TCL_ERROR);
    }

Result is:

D0/0: mode: 2308
Error in startup script: Internal Error: unknown shade style returned in
get_drawmode
    while executing
"Nvol$curr slice get_drawmode"

In
include/gsurf.h
are definitions for:

/* surface display modes */
#define DM_GOURAUD   0x00000100
#define DM_FLAT      0x00000200   /* defined for symmetry */
#define DM_FRINGE    0x00000010
#define DM_WIRE      0x00000001
#define DM_COL_WIRE  0x00000002
#define DM_POLY      0x00000004
#define DM_WIRE_POLY 0x00000008
#define DM_GRID_WIRE 0x00000400
#define DM_GRID_SURF 0x00000800

Not sure what mode = 2308 means...
