For the archives: I finally found the culprit. I had this in my
.bashrc:
---------------
if test -z "$SSH_AUTH_SOCK" ;
then ssh-agent $SHELL
fi
---------------
This causes ssh-agent to be also called in non-interactive
sessions, which somehow causes scp/sftp to fail.
This works:
---------------
if [ -z "$SSH_AUTH_SOCK" ] && [ -x /usr/bin/ssh-agent ] && /usr/bin/tty -s ;
then ssh-agent $SHELL
fi
---------------

Best
