I cannot reproduce it. Can you send me sample location or exact commands
which lead to this crash?

Comment (by msieczka):

The crash takes place when the computational region is different than
wxGUI display region.

E.g., in spearfish6:

1. Set region away from data, g.region n=2 e=2 w=1 s=1 res=1 -a.

2. Load 'elevation.dem' in wxGUI.

3. "Zoom to selected map" on it.

4. Start NVIZ - a complete wxGUI crash.

Apparently wxNVIZ depends on computational region. I think it should use
the display region.
