[orca-list] Ubuntu + Orca 3.1.3 loadBackend fails

[Malte Simon <malte_simon hotmail com>]

Hi I try to run Orca-3.1.3-xdesktop on Ubuntu 11.04 with unity and got an error:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "orca.py", line 510, in <module>
    _settingsManager = SettingsManager()
  File "/home/blub/orca/orca-3.1.3-xdesktop/src/orca/settings_manager.py", line 95, in __init__
    raise Exception('SettingsManager::_loadBackend fails.')
Exception: SettingsManager::_loadBackend fails.

any hints?
