Issue with Orca and liblouis in testing

[Alex Bernier <alex.bernier@free.fr>]

Hello, 

I use a Debian testing :
* gnome-orca 2.28.0-1
* liblouis-dev 1.7.0-1
* liblouis0 1.7.0-1
* liblouisxml-bin 2.0.0-2
* liblouisxml1 2.0.0-2
* python-louis 1.7.0-1

When I run orca, I get the following message :
<log>
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/local/lib/python2.5/site-packages/orca/orca.py", line 55, in <module>
    import braille
  File "/usr/local/lib/python2.5/site-packages/orca/braille.py", line 47, in <module>
    _defaultContractionTable = louis.getDefaultTable()
AttributeError: 'module' object has no attribute 'getDefaultTable'
</log>

If this issue is not already known, tell me if you want more precisions.

Regards,

Alex
