Comment (by quozl):

 Only the first row of the journal is affected.

 A working hack is to call Gtk.TreeView.queue_draw_area a second time with
 the same arguments via GLib.idle_add if the rectangle to redraw has a Y
 value of zero.  It is not yet known why this is needed.

 {{{
         def redraw():
             view.queue_draw_area(rect.x, rect.y, rect.width, rect.height)
             return False
         redraw()
         if rect.y == 0:
             GLib.idle_add(redraw)  # nuts, why is it so?
 }}}

 This hack may indicate the nature of the problem somehow.
