ssh-copy-id fails with redirect error

ssh-keygen seems to work ok, but when I try to use ssh-copy-id, I get this:

warning: An error occurred while redirecting file '/dev/null` ] || echo >> .ssh/authorized_keys || exit 1; } && cat >> .ssh/authori
zed_keys || exit 1; if type restorecon >/dev/null 2>&1; then restorecon -F .ssh .ssh/authorized_keys; fi'

Any help?
