Of course, what if it's arranged for name to equal
'"; rm -rf / & echo you're a loser"'
? If an attacker controls the string (eg by supplying it from e-mail or
a web page), you're sunk.
this should be safe, at least as long as run-mailcap doesn't commit the
same kind of error:
os.spawnvp(os.P_WAIT, "run-mailcap", ["run-mailcap", name])
