That one is tricky. Your server does not support inimage exceptions  
wich is the default for the direct requests. That's OK and within the  
standard, but your server does not report meaningful errors:  
"<ServiceException>Unknown error</ServiceException>".

You need to set the exception format explicit:

        - type: direct
          req:
            url: http://shagrat.icc.es/lizardtech/iserv/ows?
            layers: mtc50m
            exceptions: application/vnd.ogc.se_xml


After that you will hit the bug I mentioned yesterday. You have to  
remove line 2 and 3 of your service.yaml, you are also limited to the  
image format that is configured 'image/png' and can't set transparent  
and bgcolor. I will try to fix this bug today.


Regards,
Oliver
