gnome-cups-add silently crashes on edubuntu 6.06.1

Binary package hint: gnome-cups-manager

I can't to add printer via gnome-cups-manager. When i click "New Printer", gnome-cups-add program start, reading printer database and silently crashes. If i start gnome-cups-manager from terminal, i see warnings and X Window System error:

** (gnome-cups-add:17265): WARNING **: Two ppds have driver == 'foo2zjs (recommended)'
        ->Minolta-magicolor_2430_DL.ppd.gz (Minolta magicolor 2430 DL Foomatic/foo2zjs (recommended)[1]) and
        ->linuxprinting.org-gs-builtin/Minolta/Minolta-magicolor_2430_DL-foo2zjs.ppd (Minolta magicolor 2430 DL Foomatic/foo2zjs (recommended))[1]
The program 'gnome-cups-add' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadValue (integer parameter out of range for operation)'.
  (Details: serial 218 error_code 2 request_code 94 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.)

I think that problem in locale settings - i use ru_RU.UTF-8. If i start gnome-cups-manager from terminal by this way:

$LANG= gnome-cups-manager

all works fine.
