Yo ---
the dox of ftplib (RTFM) sez that the dir() method returns NONE
so you can't cast None to string.
but if the last argument to dir() is a function this function is
used as a callback (f.e. retrlines() *wink*).
this is taken with a grain of salt cuz i didn't check out
ftplib myself.

hope this helps
grrrrretz Jö!
