What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

Please provide any additional information below.

I'm getting the same here.

I'm using Django1.3, Python 2.7.3, Win7x64
I can't tell the exact way how to reproduce this.

I managed to fix it by making a little workaround:
on nose\plugins\capture.py we have:

    def formatError(self, test, err):
        """Add captured output to error report.
        """
        test.capturedOutput = output = self.buffer
        self._buf = None
        if not output:
            # Don't return None as that will prevent other
            # formatters from formatting and remove earlier formatters
            # formats, instead return the err we got
            return err
        ec, ev, tb = err
        return (ec, self.addCaptureToErr(ev, output), tb)

We can write it like this:

    def formatError(self, test, err):
        """Add captured output to error report.
        """
        try:
            test.capturedOutput = output = self.buffer
        except UnicodeDecodeError:
            test.capturedOutput = output = 'FOOBAR'

        self._buf = None
        if not output:
            # Don't return None as that will prevent other
            # formatters from formatting and remove earlier formatters
            # formats, instead return the err we got
            return err
        ec, ev, tb = err
        return (ec, self.addCaptureToErr(ev, output), tb)

Is it ok to do that?
I don't know if this will crash nose if something goes wild. Neither if i'm making silent errors.
