Rule of thumb: if you're using OpenStreetMap *MAPS*, you only need to 
attribute. If you're using OpenStreetMap *DATA*, share-alike applies on the 
modifications you make to that data, or on the data you add on top of it.

As you'll be using the Marble widget, I guess that you'll be using just the 
unmodified mapnik rendering of the OSM map and plot some points (or stuff) on 
top, or move the map on some event, or something like that. In that case, 
just attribute Marble and OSM and you're fine.
