[GRASSLIST:4281] can't make full res. ppm in NVIZ

[Carlos Henrique Grohmann]

Hello all,

I'm with two problems in NVIZ (GRASS 5.3 and 5.7): 

1 - I can't mask a raster to show just part of it over a DEM.

2 - when I try to make a full res. ppm, it crashes and gives me this error msg:

child killed: segmentation violation
    while executing
"exec /usr/local/grass5/grass53/etc/nviz2.2/NVWISH2.2 -f
/usr/local/grass5/grass53/etc/nviz2.2/scripts/nviz2.2_script el=topo.dem -name
NVIZ >&@stdout"
    ("eval" body line 1)
    invoked from within
"eval exec $env(GISBASE)/etc/nviz2.2/NVWISH2.2 -f

    invoked from within
"if {$argv == ""} {
#no arguments

    (file "/usr/local/grass5/grass53/bin/nviz" line 16)


thanks
