Popups: count is NaN

If I enable _OL+: Popups_ (but not _OL+: Tooltips_) the popup shown on hover displays "NaN" for the count -- printed from this:

``` javascript
text += "<div class='popup-count'>" + parseInt(feature.attributes.count, 10) + "</div>";
```

Also, when I click the popup (for a single point,) the pager section shows "1 / 0" ...
