Bug reproduction

Hi,

Marble branch: Applications/17.04
Platform: Ubuntu 16.10

I create two or more placemarks and later I update their icons by providing
new, unique QImage objects. I expect all placemarks to have those unique icons
but they are all the same.

This is how I update the icons:

QSharedPointer<GeoDataStyle> style(new GeoDataStyle(*place->style()));
auto image = QImage("/path/to/image");
style->iconStyle().setIcon(image);
place->setStyle(style);
widget->model()->treeModel()->updateFeature(place);

There is a workaround for this bug - add this line with a fake, unique path for
each image:
style->iconStyle().setIconPath("/fake/unique/path/");

See the whole code in the attachment.

Best regards,
Rafał
