xfce-panel does not come up

[houghi]

Working with openSUSE 11.4 and XFCE 4.6

I had two videocards with three monitors. For the time being I only have 1
card with two screens. However this means that I only have DISPLAY 0:0 and
DISPLAY 0:1. DISPLAY 0:2 does not exists anymore.

I think that that is the reason xfce-panel refuses to launch.

When I launch it in a terminal I see the two flash up and shut down in my
two existing DISPLAYs. The errror I get is (among other things)

The program 'xfce4-netload-plugin' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 223 error_code 3 request_code 18 minor_code 0)
   (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the
   gdk_x_error() function.)
<snip>

My guess as to what is happening is that xfce-panel treis to launch, does
not find DISPLAY 0:2 and closes down. Then all the plugins try to launch,
but are unable to find the panel.

So I already removed ~/.config/xfce/panel to get started again, but still
the same problem.

What can I do (and sorry, going to 4.8 is not an option for now) to solve
this. Ideal would be that I can save it, so when I reconnect the third
monitor, I can just put stuff back.
