Does that mean we can assume it the fact I'm running 8.04 that's causing the problem?
Upgrading to the rc has caused me nothing but trouble, I'll be patient in the future:)

Not getting a message like that.

libselinux? how odd. Unless it runs underneath the hood, I don't think I
use it.

See the last post for the symbol.

Thanks!
