playonlinux crashes at startup Ubuntu 12.04 Beta

Hello community,
I've got an issue with play on linux which I installet after the upgrade to Ubuntu 12.04 Beta.
This is the output of the command "playonlinux".
I don't know if its really a bug or just a missing dependancy, so I decided to ask you before I create a bug report.
