Have you inspected the contents of the output? As I see it, this is not the problem of your script, but rather of "Nautilus". I haven't used Nautilus ever, so couldn't help you to set up a "capable viewer", but Google tells us that you need gedit. If that fails, try: 

$ file /home/a/mail/yahoo/2512200317146

to see what kind of file you're dealing with.
