问题
I had been getting the referenced error under version 2.4 with a different lon/lat data set. I upgraded to 2.6 and was able to use 2dsphere index on that data set. However, with a different data set (excerpt below) I received the old error message on trying to index using 2dshpere. the error message excerpt is as follows:
I am having the same problem receiving the error: can't extract geokeys from object; malformed geometry?. The object is the following, which validated on on GeoJSONLint.com. Also, I am using mongodb version 2.6.1. This happened to me recently when I was using version 2.4, and I upgraded to 2.6, and that solved the problem then, but I am getting the error again with a new geojson data set. Please, if anyone can let me know how to solve that would be very helpful.

There is a bug posted for this problem: https://jira.mongodb.org/browse/SERVER-13735
“Malformed geometry” error when creating a geosphere index for a valid MultiPolygon
Similar issue, a valid GeoJSON is being submitted for a 2dsphere index and is causing the "Can't extract geo keys from object, malformed geometry?" error.
There have been a series of previous bugs where valid GeoJSON was causing this error message. They've fixed those in 2.6.x but this appears to be a new one. I'd chime in on JIRA as it will help get it prioritized for a fix.

Maybe the problem is because your polygon coordinates has the first coordinate and last coordinate as the same value. Try to remove the last coordinate pooint from your polygons.
