I think I have found the answer:

user_renderer = Gtk::CellRendererPixbuf.new
col = Gtk::TreeViewColumn.new
col.title = "pic"
col.pack_start(user_renderer, false)

pixbuf = Gdk::Pixbuf.new('/home/demas/settings/awn_icons/emacs.png')
user_renderer.set_pixbuf(pixbuf)

Or better:

iter = @store.append
iter[0] = twi.message()
iter[1] =
Gdk::Pixbuf.new('/home/demas/settings/awn_icons/emacs.png')

....

user_renderer = Gtk::CellRendererPixbuf.new
col = Gtk::TreeViewColumn.new
col.title = "pic"
col.pack_start(user_renderer, false)
col.add_attribute(user_renderer, 'pixbuf', 1)
