Hi,

maybe the bug is related to a similar one I got:

Emulation of a system without VGA will crash while switching from
serial console to monitor. I got this crash with SDL and VNC displays.

The crash is caused by a surface which is too small: your patch for
dumb terminals assumes 640 x 480 pixels, but the monitor is much
larger. So the allocated display data is too small.

Regards
Stefan
