Someone also reported that orca in conjunction with Gnome-terminal causes the 
SD crash. One common property between brltty and orca is that both work with 
Unicode whereas my guess is that the other applications work with the host 
character set. Since the screen font can contain up to 512 characters whereas 
the host character set typically only contain 256, it's possible that 
unicod-based 
screen readers are sending characters to SD which are filtered by the other 
applications. It seems, therefore, that sd->espeak is tripping over characters 
that it isn't prepared to handle.
