Issue 4539: askdirectory() in tkinter.filedialog is broken (original) (raw)
Calls to tkinter.filedialog.askdirectory() throw a KeyError if any of the options (title, text, bitmap, default, strings) are not provided.
Previously saying "askdirectory()" with no arguments would open a file browser window. Since all other functions in filedialog still function with no arguments this seems like an error. (Actually askopenfiles() seems to be broken too, saying "IOError: [Errno 2] No such file or directory: '{'")
