This is your problem here: profile should only be read for interactive sessions - the shell does this automatically for you, you should not
source it in bashrc.

Your shell initialisation for non-interactive sessions must not produce
any output. This requirement isn't unique to scp, all the tools layered
on top of rsh have it too.
