Ops, I was at 2.2 on my win machine, sorry.

Can be, I think, the connection closed by my code: into it, I close
connection ( self._myClient.quit() ) when I receive an error
(addErrback), but I have a "callLater" that are always running, so when
called, it run the code that can generate that error.
I think that I have to control the "internal connection state" before
make a call to the ftp client. I'm right? Or is there a method for say
to twisted to don't make calls (with the ftp protocol) when it aren't
connected?

P.s. Now I'm switching to twisted 2.4 :)

Thanks,
