xfce4.2 does not start

[maarten derksen]

Hello all,

I upgraded to xfce4.2 last night, using the mandrake 10.1 rpm's provided 
by  eslrahc, but i can't get it to start. Here is my .xsession-errors 
output:

/etc/X11/gdm/PreSession/Default: Registering your session with wtmp and utmp
/etc/X11/gdm/PreSession/Default: running: /usr/bin/X11/sessreg -a -w 
/var/log/wtmp -u /var/run/utmp -x "/var/lib/gdm/:0.Xservers" -h "" -l 
":0" "maarten"

/usr/bin/xfce4-session: symbol lookup error: /usr/bin/xfce4-session:

Can anyone give me a pointer as to how to solve this?
