Description
In qgsmapcanvas.cpp in QgsMapCanvas::setLayerSet a disconnect and connect call to selectionChanged signal are being made on the map layer set, but some of those layers can be raster layers. selectionChanged() is a signal that only vector layers can emit.
This bug causes warning messages to appear when calling setLayerSet via the python bindings with a layer set that contains rasters.
The solution is to wrap the disconnect and connect calls with logic to test if the layer is a vector layer.

Turns out src/app/legend/qgslegendlayerfile.cpp also contains the issue... not only for selectionChanged() but for wasModified(bool) as well. Both of these need to be connected only to vector layers. Attached is a patch to wrap all of these cases to check for vector layer.
