DoS window manager with extremely long button

[Emanuel Bronshtein]

Binary package hint: gxmessage

displaying extremely long button causes the window manager to crash.

test case :
emanuel@emanuel-desktop:~$ gxmessage text -buttons `python -c "print 'A'*115000"`

(gxmessage:8096): Gdk-WARNING **: Native Windows wider or taller than 65535 pixels are not supported
The program 'gxmessage' received an X Window System error.
This probably reflects a bug in the program.
The error was 'RenderBadPicture (invalid Picture parameter)'.
  (Details: serial 316 error_code 158 request_code 148 minor_code 23)
  (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.)

Hi - gxmessage 2.20.4 (for GTK2) and gxmessage 3.4.3 (for GTK3) both include fixes for this bug :)
