Hi,
firtst, i use libxfcegui4 4.0.6 -2suse91 from the apt-version at 
ftp://ftp.gwdg.de/pub/linux/suse/apt/SuSE/9.1-i386/RPMS.suser-ollakka/
I solved the problem now by deleting directory .enlightenment. After 
restarting enligthenment, the panel worked again.
It seems to be a problem between the desktopsettings in enlightenment 
and xfce4-panel.

In enlightenment i use 1 Desktop and 4 virtuell Desktops. First time I 
startet xfce4-panel it worked. After reducing the Desktop in xfce4 to 
one, setting the panel to autohide and giving it a iconbox-border (in 
enlightenment), it crashed after the next restart of X.
I was working for one day with xfce4 and got the idea of deleting 
.englightenment. After restarting englightenment the four desktop-picons 
of xfce4-panel reduced to one after callling the panel-settings and 
desktop nr. 4 was highlighted. I removed the desktop-icon from panel and 
now panel and enlightenment working perfect, after one reboot and 
several "startx".

Thank you for your help and ask, if you want some more information.

Michael
