xfce4-panel crash

[Sergey Manucharyan]

Hi guys!

I've just installed the XFCE.
It starts with the desktop and the following message:
==================================================
A crash occured in the panel
Please report this to the xfce4-dev at moongroup.com list
Meanwhile the panel will be restarted
==================================================
I can also start manually the xffm and run some programs.
Here is the output of xinit:
==================================================
