As there were no objections, I pushed the changes to fd.o git:
http://gitweb.freedesktop.org/?p=geoclue.git;a=commit;h=82a304331a6bd6ba438de5a73a3d968189447018

The errors and error codes are defined in
backend/geoclue_position_error.[ch]. Currently the list of error codes
for position backends looks like this:

  GEOCLUE_POSITION_ERROR_NOSERVICE,
     /* Backend cannot connect to needed service */

  GEOCLUE_POSITION_ERROR_MALFORMEDDATA,
     /* Received data, but it is unreadable */

  GEOCLUE_POSITION_ERROR_NODATA,
     /* Used service cannot provide position data at this time*/

  GEOCLUE_POSITION_ERROR_NOTSUPPORTED,
     /* Backend does not implement this method */

  GEOCLUE_POSITION_ERROR_FAILED
     /* generic fatal error */
