Hi there.

I am running Ruby 1.8.7 (debian lenny/i386) and the following program  
crashes the ruby vm with a Segmentation Fault (when closing the window):

#!/usr/bin/env ruby  
=begin  
rubycalc - Ruby/GTK first sample script.  
=end

require ‘gtk2’

window = Gtk::Window.new  
window.signal\_connect(“delete\_event”) {  
puts “delete”  
false  
}

window.signal\_connect(“destroy”) {  
puts “destroy”  
Gtk.main\_quit  
}

window.add( $tos=Gtk::Entry.new() )  
style = Gtk::RcStyle.new  
font = Pango::FontDescription.new(“Sans Serif 15”)  
style.font\_desc = font  
$tos.modify\_style(style)

window.show\_all

Gtk.main

# EOF

Am I abusing RcStyle/Pango or did I discover a bug in the GTK2 bindings?

Regards  
Holger
