Scp in init returns a "write broken pipe" error

[crile]

Hi, I try to copy a local script to my remote server in the init then execute it.

    - title: status
      #rate-ms: 60000
      multistep-init:
        - scp monit.sh raspberry:/tmp/monit.sh
        - ssh raspberry
      sample: sh /tmp/monit.sh

But the scp command seems to fail with the following error:

    SAMPLING FAILURE failed to execute command: write |1: broken pipe

All commands work properly outsite of sampler.
The monit.sh script is in the current working directory.
I also try to use absolute path with no success.

Tested on Ubuntu mate with amd-64 binary and the remote server is a raspberry pi.
