shnake: TypeError: Can't convert 'NoneType' object to str implicitly

[sndx02d]

I've tried to add autocompletion mechanism to some file related plugins (the idea - after running "ls", the "cat" plugin, or any other plugin, will have autocompletion for the remote files and dirs):

\phpsploit\src\ui\interface.py:

    def complete_cat(self, text, *_):
        return [x for x in session.TargetFiles if x.startswith(text)]

\phpsploit\src\core\session__init__.py:

        self.File = None
        self.TargetFiles = []

    def _isattr(self, name):

\phpsploit\plugins\file_system\ls\plugin.py:

    rows = sorted(rows, key=(lambda elem: elem[-1]))

    for file in rows:
        file = file[3]
        if file != "." and file != "..":
            session.TargetFiles.append(target + file)

    rows.insert(0, rows_hdr)

When I'm testing it, it's never working as it supposed to work, and behaving very strange:

maybe related to backslashes, need to see readline internals to be sure.
i d suggest to try on a Linux target server, or trying with normalized paths (phpsploit recognises windows paths even using normal slashes) to check if that's related to backslashes ''
