Dear list,
I don't no why happening this traceback error messages in Orca with
Ubuntu 13.10, GNOME Shell classic session when I want editing the
/boot/grub/grub.cfg file in Gedit:
First traceback:
Traceback (most recent call last):

return _lines[viewport[1]]
IndexError: list index out of range
Reproducation steps with I always reproduced the issue if in Orca
preferences the braille support is enabled:
1. Open in gedit the /boot/grub/grub.cfg file.
2. Press CTRL+END keystroke.
3. Press few up arrow keys. After two up arrow keypress my braille
display presenting the "screen not in text mode" text.
I experienced this issue both Ubuntu factory level packaged Brltty
version and latest svn build.
When I installed with svn build, I ran ./autogen script with
--prefix=/usr parameter, do a normal make >/dev/NULL and a make install
>/dev/NULL command.
I builded and installed the Python bindings both Python 2.7 and Python 3.3.
The brlapi.auto.c file in the 6951 line have following code:
{__pyx_filename = __pyx_f[0]; __pyx_lineno = 551; __pyx_clineno =
__LINE__; goto __pyx_L1_error;}
In the 551th line have following code this file:
#define __Pyx_RefNannyFinishContext() \
__Pyx_RefNanny->FinishContext(&__pyx_refnanny)
The /etc/brlapi.key file have following permissions factory level
without I anything doed this file:
-rw-r--r-- 1 root root 33 okt 16 21:03 /etc/brlapi.key
I using Orca master branch version. This problem my machine independent
happening if turned on with orca the contracted braille or not. I using
in Brltty console mode the hu.ttb text table. When contracted braille is
enabled, I using Liblouis hu-hu-g1.ctb hungarian grade1 table.
I attaching my /etc/brltty.conf file with I saved my oldest Ubuntu 12.04
installation. Hopefuly not this file producing the problem.
I already reported this issue in Orca side with Bugzilla, report link is
following:
https://bugzilla.gnome.org/show_bug.cgi?id=712815
If need any other tests with help fixing the bug, please tell me the
testing steps and I will be doing required testings.

# This is a configuration file template for the BRLTTY application.
# Uncomment those entries which apply to your personal needs and system
# requirements.
# BRLTTY expects to find its configuration file in "/etc/brltty.conf"
# (can be overridden with the -f [--configuration-file=] option).
# If it doesn't exist, then BRLTTY silently continues but may require
# that certain command line options be explicitly supplied.
# Blank lines are ignored. The character '#', anywhere on a line,
# initiates a comment; all characters from it to the end of that line
# are ignored.
# Each configuration entry consists of a keyword followed by its operand.
# An arbitrary amount of white space, (blanks and/or tabs), may occur
# before the keyword, as well as before and after the operand. Keyword
# processing is not case sensitive. Examples of valid entries are:
#
# Braille-Driver pm # Papenmeier braille displays.
# braille-device serial: # The first serial device.
# SPEECH-DRIVER fv # The Festival Text to Speech System.
# The default settings given within the following descriptions assume no
# special build options (see "./configure --help" in the top-level
