[GRASS5] nviz crashing in pre1

[Helena Mitasova]

Has anybody tested nviz in 5.0pre1? It has a strange behavior - if I
start it with -x flag it runs fine. If I start it with -q or a given
elevation file it crashes everything and logs me out. However, -q and
elevation
runs OK if nviz was run with -x flag first. So it seems that -x option
sets something which is missing
in the other options. Or am I missing something here? I am running it
with RedHat 7.1
I am not sure whether this is a bug or I don't have something set up
properly.

thanks, Helena
