That is weird: in sane Posixy system writing to '/dev/null' works
while writing to other destination may fail or block. I am
not sure if ignoring error output in this case is a good
idea, but the change looks like "fooling around" a bug,
which on one system may avoid triggering a bug, but
on another actually could trigger (possibly different) a bug.
