pitivi complain about one of osssink or alsasink missing

[Popolon]

when pitivi is launched, it complain about missing osssink or alsasink, but launching it in a terminal, it also complains about jack-server missing.

Cannot connect to server socket err = No such file or directory
Cannot connect to server socket
jack server is not running or cannot be started

installing jack package resolve the problem. This looks like a dependency bug.
