 It seems the recent support for mixing Google/Bing/OSM layers with a
 partial/fully tiled Map Definition has broken the existing support for
 untiled Map Definitions.

 Reproduction steps:

  - Load Sheboygan Dataset
  - Edit Sheboygan Map Definition's coordinate system to
 WGS84.PseudoMercator
  - Create a new Fusion Application Definition
  - Enable any commerical layer
  - Preview the Application Definition

 Results:
  - [Any or all Bing Layers]: Bing map centered on USA, get error

  - [Any or all Google Layers]: Sheboygan map shows, no google imagery
 available
  - [Any or all OSM Layers]: Sheboygan map shows, no OSM tiles display.
 Firebug shows lots of 404 requests to tile.openstreetmap.org

 As soon as you introduce a tiled layer into the Map Definition with a
 Google-compatible finite scale list. The commercial layers line up with
 the Sheboygan map.
