Re: [Tracker] Querying values of metadata keys

[Iago Toral Quiroga <itoral igalia com>]

Hi,

tested the original patch against r1241. Now it does not make the daemon
segfault, but still I do not get any results. This is what I'm doing:

  char *keys[] = {"Audio:Title", NULL};

  char **result =
    tracker_metadata_get (tc, SERVICE_MUSIC,
                          "path/to/mp3/file",
                          keys, &error);

/* I get a proper value for the clip title */

  result = 
    tracker_metadata_get_unique_values (tc, "Audio:Title", 0, 10, 
                                        &error);

/* I get and empty array */
