[linux-audio-user] Could not connect to JACK server as client

Hi people !

I gonna be clearest as possible !

My system : debian sarge, gnome, 2.6.14-2 homemade kernel.

Before : (Just an abstract) Ardour (0.9beta28 debian version)
                            Jack (0.99 debian version)
                            Qjackctl (0.2.15a debian version)

I was building new version of ardour (0.99.2) from sources, it was build
in /usr/local a separate partition.
I tryed and it works. So i built jack (0.100) from source too. It was
okay so

Know : Ardour (0.9beta28 debian version)
       Jack (0.99 debian version)
       Qjackctl (0.2.15a debian version)
plus
       Ardour (0.99.2)
       Jack (0.100) installed in /usr/local.

But, and this the trouble when i start Qjackctl
(with /usr/local/bin/jackd in the setup path) i've got this message :

(As you see there's the time in Paris :))

Same if i start Qjackctl under root.

If i try to launch Qjackctl with the default path setup (/usr/bin/jackd)
i've got a segmentation fault.

Is there someone who have a idea, what can i do ?

Merci d'avance, best regards

P'tit Louis.
