Hello again,

as I said before, it works with the newest version from the repo. 
Unfortunately the requirement is to use the version provided by Ubuntu 
12.04 ( 0.17-0ubuntu1) or even 10.04 (0.16-0.1).

Can anybody tell me what changed between this versions and is there a 
way to get this working with the older version?

Best regards,
Patrick
