Hello, I've noted a problem with blender. Could some folks with the new 4.0 try this:

Run blender (any one of the three apps in Knoppix)
Add--> Meta--> Metaball
Render-->Render Current Frame

Does the app crash?

I've "never" seen this happen with blender:
i) installed to HDD with a HDD install of Kanotix 2005-03
ii) installed to HDD with a WinXP desktop
iii) [two other examples deleted with sincere apologies.]

But it was happening repeatedly, but not on every machine, with knoppix 4.0-2005-08-16
