The VGA adapter isn't the only thing being displayed on the SDL/VNC display - you potentially have the monitor console, and serial / parallel devices & anything else that's using one of QEMU's text consoles. So it is correct that '-vga none' is independant of '-nographic' & thus it is neccessary to fix the crash seen.
