When using globe projection, left-right movements are inverted.

Reproducible: Always

Steps to Reproduce:
1) Enable "globe" wallpaper type
2) select projection:flat map, movement: interactive
3) (optional ?) select OSM map them and zoom in to local area
4) move around by click+draging on the desktop
5) select globe projection and retry moving around

Actual Results:  
Flatmap and mercator projections work fine: the map follows the mouse cursor as long as the drag operation continues.

Globe projection works fine for north-south (up-down) movements, but east-west movements are inverted (left for east and right for west).

Expected Results:  
"left=west, right=east" mapping

North-south dragging isn't exact in mercator/globe projections (the map moves faster than the cursor), but this bug exists in marble too and is not very bothersome.
