Closed Issue: ListPicker issue adding more than five elements [9412]

When adding elements in the xaml file everything goes ok until the 6º element, at that moment I get an exception and it doesn't show in the list.

The way I use the ListPicker is as follow:

toolkit:ListPicker >
<toolkit:ListPickerItem Name="circular" Content="circular mil" Style="{StaticResource style}" />
............

</toolkit:ListPicker>
