Solve the following python programming problem given the following code:
def get_filename(hwnd = None, start_folder = None) : 
    "Quick interface to the shell's browse-for-folder dialog,
    optionally starting in a particular folder and allowing file
    and share selection.

    ..    warning::
            At present this interacts badly with TortoiseHg, causing the
            interpreter to stack dump.
    " 
    def _set_start_folder(hwnd, msg, lp, data) : 
        if ((msg == BFFM.INITIALIZED) and data) : 
            SendMessage (hwnd, BFFM.SETSELECTION, 1, utils.string_as_pointer (data)) 
pythoncom.CoInitialize () 
    try : 
        (pidl, display_name, image_list) = wrapped (shell.SHBrowseForFolder, hwnd, None, 'Select a file or folder', ((BIF.BROWSEINCLUDEFILES | BIF.USENEWUI) | BIF.SHAREABLE), (_set_start_folder if start_folder else None), _set_start_folder) 
finally : 
        pythoncom.CoUninitialize () 
if ((pidl, display_name, image_list) == (None, None, None)) : 
        return None 
else : 
        return wrapped (shell.SHGetPathFromIDList, pidl) 

    
    

    Fix the buggy line: (pidl, display_name, image_list) = wrapped (shell.SHBrowseForFolder, hwnd, None, 'Select a file or folder', ((BIF.BROWSEINCLUDEFILES | BIF.USENEWUI) | BIF.SHAREABLE), (_set_start_folder if start_folder else None), _set_start_folder)
