Looking at the backtrace and remembering my rusty python,
I think $LANG should be irrelevant here.
It looks like Python is trying to decode an UTF-8
string and fails because the string is encoded invalid.

Maybe Orca is just missing a try/catch block to correctly catch utf-8
decode errors?

The error happens at src/orca/braille.py:356 (relative to orca source

The code looks something like:

        # The uncontracted string for the line.
        self.rawLine = string.decode("UTF-8").strip("\n")

Maybe something like:

        # The uncontracted string for the line.
            self.rawLine = string.decode("UTF-8").strip("\n")
        except UnicodeDecodeError:

Could "fix" this problem.

It would be interesting to see the actual string which fails though.
So its probably more useful to change the except-block
to something which prints the string in question to the debug log.
