Title:
  DoS window manager with extremely long error

Status in “compiz” package in Ubuntu:
  New

Bug description:
  Binary package hint: vinagre

  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:~$ vinagre --file=`python -c "print
  'A'*115000"`

  (vinagre:8697): Gdk-WARNING **: Native Windows wider or taller than 65535 pixels are not supported
  vinagre: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.0.

  sometimes it print other messages :

  emanuel@emanuel-desktop:~$ vinagre --file=`python -c "print
  'A'*115000"`

  (vinagre:8766): Gdk-WARNING **: Native Windows wider or taller than 65535 pixels are not supported
  The program 'vinagre' received an X Window System error.
  This probably reflects a bug in the program.
  The error was 'RenderBadPicture (invalid Picture parameter)'.
    (Details: serial 313 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.)
