Cannot launch rename operation from terminal only

From what I understand, Metamorphose is supposed to be able to be run from the CLI interface without ever seeing the GUI, is this correct?

I used the GUI to create myself some config files for later reference over the CLI, but whenever I launch metamorphose with the -c and -p arguments at the same time, it crashes.

Example: metamorphose2 -p=/root/Desktop/Test_Folder -c=/root/Desktop/test_configuration.cfg -a=3

This is the output I get:

Auto mode level set: 3 Traceback (most recent call last): File "/usr/share/metamorphose2/metamorphose2.py", line 188, in main(wx_version, cli_options) File "/usr/share/metamorphose2/metamorphose2.py", line 182, in main application = BoaApp(0) File "/usr/lib/python2.7/dist-packages/wx-3.0-gtk2/wx/_core.py", line 8628, in init self._BootstrapApp() File "/usr/lib/python2.7/dist-packages/wx-3.0-gtk2/wx/_core.py", line 8196, in _BootstrapApp return core.PyAppBootstrapApp(*args, **kwargs) File "/usr/share/metamorphose2/metamorphose2.py", line 177, in OnInit self.main = MainWindow.create(None, cli_options) File "/usr/share/metamorphose2/MainWindow/init.py", line 45, in create return MainWindow(parent, options) File "/usr/share/metamorphose2/MainWindow/init.py", line 600, in init self.picker.set_path(True) File "/usr/share/metamorphose2/picker/init.py", line 132, in set_path self.refresh(True) File "/usr/share/metamorphose2/picker/init.py", line 369, in refresh self.select_all() File "/usr/share/metamorphose2/picker/init.py", line 112, in select_all self.view.select_all(event) File "/usr/share/metamorphose2/picker/wxPickerView.py", line 625, in select_all main.show_preview(event) File "/usr/share/metamorphose2/MainWindow/init.py", line 620, in show_preview self.on_preview_button(False) File "/usr/share/metamorphose2/MainWindow/init.py", line 922, in on_preview_button self.renamer.preview(event) File "/usr/share/metamorphose2/renamer/init.py", line 72, in preview self.__preview.generate_names(event) File "/usr/share/metamorphose2/renamer/preview.py", line 225, in generate_names self.run(operations) File "/usr/share/metamorphose2/renamer/preview.py", line 304, in run newExt, itemToRename) File "/usr/share/metamorphose2/operations/insert.py", line 68, in rename_item parsedText = operations.parse_input(insert.Text.GetValue(), original, self) File "/usr/share/metamorphose2/operations/opButtons.py", line 185, in parse_input return self.parser.parse_input(text, file, operation) File "/usr/share/metamorphose2/operations/opParser.py", line 439, in parse_input value = self.date_time(0, file, operation) File "/usr/share/metamorphose2/operations/opParser.py", line 296, in __date_time return utils.udate(main, dateTime[op + 1], itemDateTime) File "/usr/share/metamorphose2/utils.py", line 208, in udate udate = time.strftime(format.encode(main.encoding), itemDateTime) LookupError: unknown encoding: None

I have no idea if this is due to something I'm doing wrong, or where exactly a potential bug could be. Any ideas?

For reference, this is the content of my config file, test_configuration.cfg:

Overall I love Metamorphose and would love to see it grow, it's exactly the kind of program I needed, so major kudos for making it. Please help us help make this thing even better :)
