DoS window manager with extremely long error

[Emanuel Bronshtein]

Binary package hint: zenity

displaying extremely long error causes the window manager to crash.
if the keyboard doesn't respond , login in tty and run "compiz&" .

test case :
emanuel@emanuel-desktop:~$ zenity --error --text=`python -c "print 'A'*115000"`

(zenity:8369): Gdk-WARNING **: Native Windows wider or taller than 65535 pixels are not supported
The program 'zenity' received an X Window System error.
This probably reflects a bug in the program.
The error was 'RenderBadPicture (invalid Picture parameter)'.
  (Details: serial 266 error_code 158 request_code 148 minor_code 8)
  (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.)

sometimes it print other messages :

emanuel@emanuel-desktop:~$ zenity --error --text=`python -c "print 'A'*115000"`

(zenity:8406): Gdk-WARNING **: Native Windows wider or taller than 65535 pixels are not supported
zenity: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.0.
