The standard RSS update with XmlListModel/ListView does not work by some reason. After some time, the ListView gets out of sync with the XMLListModel and it shows wrong content (already deleted emails, nothing at all etc.). It maybe caused by some incorrect "id" field in the RSS entries? I don't know, but if the "id" as key removed from the model, the all items are always updated in the RSS fetch causing "new email arrived" messages always The current workaround contains two XmlListModels, one to calculate the correct amount of new emails with "id" as key and a second without "id" associated with the ListView. Since the second updates all items always, it is unlikely that the ListView goes out-of-sync.

I know this is not a correct fix just a workaround, but I could not come up anything better without extensive debugging since the original implementation is simple and it should not have any problem.
