Crashes in dconf I believe.

conf-watcher.c is in gnome-settings-daemon code:

static void
settings_changed_cb (GSettings *settings,
                     const gchar *key,
                     ConfWatcher *watcher)
{
        const gchar *gconf_key_name;

        gconf_key_name = g_hash_table_lookup (watcher->keys_hash, key);
        if (gconf_key_name != NULL) {
                GVariant *value;

Comment 3 Bastien Nocera 2011-09-12 10:19:32 UTC

That's the GConf plugin.

Comment 4 Rodrigo Moya 2011-09-13 08:58:31 UTC

Fixed in git master
