How reproducible:

Steps to Reproduce:
1. In a terminal, launch git-cola


Actual results:
Traceback (most recent call last):
  File "/usr/bin/git-cola", line 56, in <module>
    sys.exit(main())
  File "/usr/share/git-cola/lib/cola/main.py", line 37, in main
    return args.func(args)

    view = MainView(context.model, settings=args.settings)

    result = standard.MainWindow.apply_state(self, state)
  File "/usr/share/git-cola/lib/cola/widgets/standard.py", line 133, in apply_state
    from_base64(str(windowstate)),
TypeError: arguments did not match any overloaded call:

  fromBase64(Union[QByteArray, bytes, bytearray], Union[QByteArray.Base64Options, QByteArray.Base64Option]): argument 1 has unexpected type 'str'



Expected results:
git-cola restore the previous repository.
