Handle broken or incomplete views more gracefully

[Krzysztof Klimonda]

malformed (or incomplete) views seem to confuse couchdb-glib which starts throwing lots of Critical messages like that:
(process:4377): Json-CRITICAL **: json_object_get_object_member: assertion `JSON_NODE_TYPE (node) == JSON_NODE_OBJECT' failed

(process:4377): Json-CRITICAL **: json_object_get_string_member: assertion `object != NULL' failed

(process:4377): GLib-CRITICAL **: g_str_has_prefix: assertion `str != NULL' failed

(process:4377): Json-CRITICAL **: json_object_has_member: assertion `object != NULL' failed

(process:4377): GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT (object)' failed

(process:4377): Json-CRITICAL **: json_object_ref: assertion `object != NULL' failed

(process:4377): Json-CRITICAL **: json_object_set_string_member: assertion `object != NULL' failed

handle such case more gracefully.

Even after I've tweaked my code some more I still get following messages:

(process:4001): Json-CRITICAL **: json_object_get_string_member: assertion `node != NULL' failed

(process:4001): GLib-CRITICAL **: g_str_has_prefix: assertion `str != NULL' failed

(process:4001): GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT (object)' failed

The request sent to couchdb looks like this:
http://127.0.0.1:5984/kangaroo/_design/channel/_view/all_channels?key=["http://planet.ubuntu.com/"]

view is:
function(doc) {
  if (doc.type == "channel")
    emit([doc.gobject.homepage], doc);
}

and the Json Document that couchdb returns:
{
    "total_rows": 1,
    "offset": 0,
    "rows": [
        {
            "id": "124ea9f53911132fe958dd10500061f9",
            "key": [
                "http://planet.ubuntu.com/"
            ],
            "value": {
                "_id": "124ea9f53911132fe958dd10500061f9",
                "_rev": "1-1a216d57f81a2a833298ffaed26ea33c",
                "type": "channel",
                "gobject": {
                    "title": "Planet Ubuntu",
                    "homepage": "http://planet.ubuntu.com/",
                    "description": "(...)",
                    "image": null,
                    "language": "en",
                    "category": null,
                    "copyright": null,
                    "editor": null,
                    "webmaster": null,
                    "generator": null
                }
            }
        }
    ]
}

It's going to get fixed once the branch I'm working on is finished and merged
