Short description of error
Dolly (ctrl+shift+MMB) changes the 3d view rotation point. It should handle it like the regular scroll-zoom as long as possible (until the 3d view's camera passes it or something like that) in my opinion. Maybe this is a feature, maybe it's a bug.. I don't know.
Exact steps for others to reproduce the error
Open the default startup file. Rotate the view with MMB.. The center is in the cube. Dolly with ctrl+shift+MMB. Rotate again.. The point is not in the middle of the cube anymore.
