I think I found a regression in RC1. The following mapproxy.yaml file
does work fine in 0.9.0b2, but it doesn't work since 0.9.0rc1:

services:
    #  demo: # Only supported since 0.9.0rc1
    # needs no arguments
  tms:
    # needs no arguments
  kml:
    # needs no arguments
  wms:
    srs: ['EPSG:900913']
    image_formats: ['image/png']
    md:
      # metadata used in capabilities documents
      title: MapProxy Geoimage.at Proxy
      access_constraints:
        This service can only be used for Mapproxy testing.
        Geoimage.at access constrains prohibit cascading & bulk download.
        So be careful not to violate their terms of use.
        More info can be found at http://geoimage.at/geoimage/geodatendienste

In rc1 and the current mapproxy repository version I end up with a
broken geoimage layer as soon as I try to  zoom onto Austria:
