New crash information added by DrKonqi

marble (2.2.20 (2.3 development version)) using Qt 5.10.1

Crash with latest master (19dbd3f1a480b45bd78b8747b1fc2d3f9b20ec79) in
Lambert-Azimuthal projection when panning the globe. The whole width of the
globe was just visible, maybe 1-2 pixels black border toward the edges.
