[ruby-gnome2-devel-en] crash with gnome gui and Kernel.exec

[euoar <eu...@ya...>]

Hello,

I'm writing an interface for a command line utility. When I press a 
start button, the callback calls Kernel.exec to make use of the command 
line utility, passing to it the information collected from the UI. Well, 
that's what I wanted to do, cause what really happens is that the new 
process (the command line utility) starts, but the GUI crashes, without 
any message... Any ideas of why could be happening this crash? I've 
tried also making a thread for the Kernel.exec part, but it crashes too...

Here is the method that doesn't work:

def button2_clicked(widget)
    nombre_destino = @entry1.text
    pelicula = @filechooserbutton1.filename
    subtitulos = @filechooserbutton2.filename
    size = @spinbutton1.value
    @thread = Thread.new {
       begin
         exec("mencoder -sub '#{subtitulos}' -subfont-text-scale #{size} 
" +
          "'#{pelicula}' -ovc lavc -lavcopts " +
          "vcodec=mpeg4:vhq:vbitrate=1000 -oac mp3lame " +
          "-lameopts br=256:vol=1 -ffourcc DIVX -o '#{nombre_destino}'")
       rescue
         puts "error"
       end
    }
  end


Thank you very much for your help.
