I tried and this is what I got:

[2004-10-06 05:51:35] uid=0(root) gid=0(root) 
groups=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel),11(floppy),20(dialout),26(tape),27(video)

_=/usr/bin/env
tar: /dev/nst0: Cannot open: Input/output error
tar: Error is not recoverable: exiting now


I agree there is a big difference from the "normal" bash:

uid=0(root) gid=0(root) 
grupper=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel),11(floppy),20(dialout),26(tape),27(video)

But I can't figure out which one is triggering the problem.
