[R-sig-Geo] rgdal readOGR() problem

[Philip Greenwood]

I am trying to compute distance spatial weight matrices using rgdal. This works fine in my local test system, but when I deploy my code to our production system I receive the following error when readOGR is executed:

Source: "/tmp/geojson_writer2529085113493086718.json", layer: "OGRGeoJSON"
with 195 features
It has 26 fields, of which 1 list fields
Error : length(fldnms1) == nflds is not TRUE

Any ideas about what the error means?

My local system and the production system are using the same version of rgdal.
Here is the sessionInfo for the system that is having trouble:
