Better error message on YAML syntax error

[phanect]

I'm using robo 0.3.0 and prepared following YAML file.

robo.yml

runsql:
  summary: Run SQL
  command: |
    # ...
    if [ ! mysql --host "$db_server_ip" --user root --password --execute << _SQL_
      # SQL...
_SQL_ ]; then # This YAML syntax error causes the error
      echo "Failed to login"
    fi

I cded to the directory where above YAML file is and run robo setup, then follwing error is shown:

$ robo runsql
panic: runtime error: invalid memory address or nil pointer dereference

This error is derived from YAML syntax error commented in above YAML file.
I would like better error message.

I'm on Kubuntu 15.04 64bit
