GeoJSON files are sometimes created in other coordinate systems apart from WGS84 LL.
Here is one such file created with FME.
{ "type" : "FeatureCollection", "features" : [...], "name" : "", "crs" : { "type" : "name", "properties" : { "name" : "EPSG:3857" } } }
mapnik-omnivore reports this as
center: [ 14989880.5561838, -3332365.289841385 ], extent: [ 12916705.4616073, -5263291.3207374, 17063055.6507603, -1401439.25894537 ], minzoom: 0, maxzoom: 6, projection: '+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs',
reading the CRS isn't straightforward, either crs.properties.name will be a legacy value like an EPSG code in which case anything except EPSG:4326 could be rejected, or it could be an OGC CRS URNs such as "urn:ogc:def:crs:OGC:1.3:CRS84".
