 ( source:grass/trunk/visualization/nviz/src/nviz_init.c, r40784)

 I tried with DEBUG=2 but it dies before getting to the `G_debug(2,
 "nviz_init:arg*` lines in nviz_init.c.

 It dies in the same way on trunk + linux too.

  * "nviz" by itself on the command line dies with a segfault:
 (all versions, all platforms)

 what does ~/.nvizrc do? it is just ~/.nvwishrc by another name?

 to be honest nviz's startup method is (and always has been) about as
 confusing to me as the custom osgeo4w grass64.bat startup method is. I
 think I need to slowly draw out a large flowchart for both :)


 thanks,
 Hamish
