v2880 groups act strange in service

[Johnthan]

Windows 10 32 bit
Trunk Version 2880
startup command python run_openlp.py

Load 3 images without a group into images
Load 3 more images with a group into images

add the first 3 images to the service one at a time
add the group of images to the service below the first three images

double click the first image in the service
Use the keyboard to move through the images

When you get to the group of images, pay attention to the live view, the live preview in the main window and the order of the images in the group. When you transition from the single images to the group of images, the last image in the group is displayed. if you move down one more image (using the keyboard) the middle image in the group is displayed....if you "go back" one image you will now see the first image in the group.

This does not happen on a clean install of trunk 2892
