X-window-manager problem

[Sébastien Valsemey <sebastien.valsemey@orange.fr>]

Hello, 

I'd like to have help on an error message I obtain when launching my
X-Session. My X-Server is well configured and is working fine.
Everything was also working fine, until I upgraded my system with
apt-get. Now, when I want to start my X-Session, the server immediately
quits with this line in ~/.xsession-errors (no matter which user it is):


/usr/X11R6/lib/X11/xdm/Xsession: /usr/bin/ssh-agent  x-window-manager:
No such file or directory

I'd like to know why. 

Best regards, 
Sébastien Valsemey.
