You forgot to say what python version, and what OS you're running on.

I havne't played much with the ftp library, but it seems it'd be much 
more robust to use something like  file[39:]   but that's still a "magic 

So i look in the ftplib docs:

and it seems there are other choices besides nlst().  If all you need is 
the filename, why not check out

FTP.retrlines(command[, callback])¶
FTP.dir(argument[, ...])
