Missing support for geolocation fields

Hi,

I am not able to make synchronous retrieve calls via the metadata API to objects with Geolocation fields in it. Is it possible to extend the WSC to include these fields? Everytime I make such a call on such an object, I am getting the following error message:
`unable to find end tag at: START_TAG seen ...... @1:5165`
This is basically the code throwing this error (object "Account" has a Geolocation field):
`...
connection = com.sforce.soap.partner.Connector.newConnection(config); metadataConfig.setSessionId(connection.getSessionHeader().getSessionId());
MetadataConnection metadataConnection = com.sforce.soap.metadata.Connector.newConnection(metadataConfig);
...
ReadResult readResult = metadataConnection.readMetadata("CustomObject", new String[]{"Account"});
--> Error`

Any help would be appreciated.

Thanks, Joachim
