[orca-list] A mistific braille refreshing issue in Orca master and posible Orca gnome-3-14 branch version

[Hammer Attila <hammera pickup hu>]

Hi,

I see an interesting braille related issue, please anybody confirm:
If I not reverting following commit, Orca doesn't refresh the braille 
display content, doesn't show cursor change, etc:

    Add support for XDG_VTNR for braille

    https://bugzilla.gnome.org/show_bug.cgi?id=744145

If I reverting this commit, my braille display again works well (show 
right the cursor changes, when I do window switch right shows the actual 
focused window).
I using Ubuntu 14.04.2 version.
The very interesting thing is following:
When I creating a debug.out file, I see following initialization message 
with braille related:
Braille module has been initialized using XDG_VTNR=7

This is correct, because my braille display I using the TTY7 terminal by 
default in the graphic session.
