What happens is the following. In the context of line 7767, arg= u'-catr:Венгрия' (type=Unicode). The line then tries to *decode* a Unicode string, which makes no sense: you can only decode a str representation. The sensible solution would be to add a check, for instance something like return arg is isinstance(arg, unicode) else unicode(arg, config.console_encoding) (which mght not work for python 2.4, though, so having a normal if/else might be preferrable).
