```
fmt.Println("Current path:", curpath)
var innerfiles []string
if innerfiles, err = ftp.List(""); err != nil {
panic(err)
}
```

returns:

panic: open /40610/40610_3286561_68607792_cmp.xml.gz: no such file or directory

despite listing all the correct files, accessing the correct directory and the file existing, i am told it cannot open a non existent file? What's happening here?
