[MapProxy] mapproxy + osm setup issue

[Kenneth Dombrowski]

Good afternoon everyone,

I have MapProxy almost working with OpenStreetMap, but something is
still misconfigured.  I am out of ideas & would appreciate any tips.

OSM itself works when I take mapproxy out of the picture by pointing my
app to the upstream servers: 

   var mqtileUrl = 'http://tile.openstreetmap.org/{z}/{x}/{y}.png';

which results in, for example, this successful request:

  http://tile.openstreetmap.org/13/3913/3336.png

When I reconfigure my app to use my mapproxy instance @ 

  var mqtileUrl = 'http://media-map.ylayali.net/mapproxy/tms/1.0.0/osm/{z}/{x}/{y}.png';

and mapproxy.yaml to use the above working url for my upstream source:

  sources:
     osm_tiles:
       type: tile
       url:  http://tile.openstreetmap.org/%(tms_path)s.%(format)s
       grid: osm_gri

I get nothing but blue squares.  The new config results in this series of activity:

==> /srv/mediagoblin/var/log/apache/mapproxy-access.log <==
[15/Oct/2012:14:33:46 -0400] "GET /mapproxy/tms/1.0.0/osm/13/3913/3336.png HTTP/1.1" 200 418

(good so far, leaflet is making the expected request)

==> /srv/mediagoblin/var/log/source-requests.log <==
[2012-10-15 14:33:47,107] GET http://tile.openstreetmap.org/14/3913/13047.png 200 0.1 324

huh?  what happened to the tms_path here?  was it translated to
something else?

==> /srv/mediagoblin/var/log/mapproxy.log <==
2012-10-15 14:33:47,108 - DEBUG - mapproxy.cache.file - writing (3913, 3336, 14) to 
    /srv/mediagoblin/mg-mapproxy/./cache_data/osm_cache_EPSG900913/14/000/003/913/000/003/336.png

I am using the `paste serve paste.ini` deployment style & connecting via
the apache FastCGIExternalServer example client.  MapProxy version 1.4.0, 
Python 2.6.6, on Debian 6.0

Thanks for reading,
Kenneth

Where /srv/mediagoblin/mg-mapproxy/tmp/ is an empty directory &
mapproxy.fcgi is my "madeup" file node
