I am not certain about this but I *think* this might be a bug in shuf.

Isn't that a bug in glibc freopen? It shouldn't fail ... merely because stdin doesn't have a valid file descriptor. If so, we should fix the Gnulib freopen module to work around the bug.

I did that, by installing the attached patches into Gnulib (first patch) and into Coreutils (2nd and 3rd patches). This fixes the shuf bug for me, so closing the bug report. CC'ing to bug-gnulib due to the Gnulib fix.
