[GRASS5] nviz segfault with grass5.7.0

[Soeren Gebbert]

Dear developers,
i have a problem with nviz, if i try to visualize a rasterfile i get a
segmentationfault:

Loading Data
child killed: segmentation violation
    while executing
"exec /usr/local/grass-5.7.0/etc/nviz2.2/NVWISH2.2 -f
/usr/local/grass-5.7.0/etc
/nviz2.2/scripts/nviz2.2_script -q -name NVIZ >&@stdout"
    ("eval" body line 1)
    invoked from within
"eval exec $env(GISBASE)/etc/nviz2.2/NVWISH2.2 -f
$env(GISBASE)/etc/nviz2.2/scri
pts/nviz2.2_script $argv -name NVIZ >&@stdout"
    invoked from within
"if {$argv == ""} {
#no arguments
eval exec $env(GISBASE)/etc/nviz2.2/NVWISH2.2 -f
$env(GISBASE)/etc/nviz2.2/scrip
ts/nviz2.2_script -name NVIZ >&@stdo..."
    (file "/usr/local/grass-5.7.0/bin/nviz" line 16)

The problem shows up only with rasterfiles.
I think the reason is, that i running a 64Bit
Linux on AMD 3000+ 64Bit. Do you have any hints to solve the problem?
I'm a skilled C-programmer, maybe i can help you?

Best regards
