crash ubuntu sofrware center

[Daniele]

is the first time I make a bug reporting and "xorg (Ubuntu) bug reporting" maybe is not the right guidelines... sorry

i'm using Lubuntu 11.10 "Oneiric Ocelot" - Beta i386
i have ubuntu software center installed; but it does't work.

from terminal
dandan@dandan-AMILO-Pa-2548:~$ /usr/bin/software-center %u

(software-center:7430): Gdk-WARNING **: The program 'software-center' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 5885 error_code 3 request_code 20 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.)

thanks

Status changed to 'Confirmed' because the bug affects multiple users.

The following command seem to fix the problem to me(running lubuntu 11.10) `sudo apt-get install gnome-themes-standard`

I saw the fix at http://osdir.com/ml/ubuntu-bugs/2011-11/msg09374.html
