Comment 24 for bug 125003

Ubuntu Lucid 10.4 LTS here.

gian@hp-gls:~$ gfax
Exception in Gtk# callback delegate
  Note: Applications can use GLib.ExceptionManager.UnhandledException to handle the exception.
System.NullReferenceException: Object reference not set to an instance of an object
  at gfax.G_ListView.DateTimeColumnDataHandler (Gtk.TreeViewColumn column, Gtk.CellRenderer cell, TreeModel model, TreeIter iter) [0x00000]
  at GtkSharp.TreeCellDataFuncWrapper.NativeCallback (IntPtr tree_column, IntPtr cell, IntPtr tree_model, IntPtr iter, IntPtr data) [0x00000]
   at GLib.ExceptionManager.RaiseUnhandledException(System.Exception e, Boolean is_terminal)
   at GtkSharp.TreeCellDataFuncWrapper.NativeCallback(IntPtr tree_column, IntPtr cell, IntPtr tree_model, IntPtr iter, IntPtr data)
   at Gtk.ListStore.gtk_list_store_append(IntPtr , IntPtr )
   at Gtk.ListStore.Append()
   at Gtk.ListStore.AppendValues(System.Array values)
   at Gtk.ListStore.AppendValues(System.Object[] values)
   at gfax.G_ListView.AddTextToRow(System.Object[] args)
   at gfax.Gfax..ctor(System.String fname, System.String[] args)
   at gfax.gfax.Main(System.String[] args)

Is there a workaround?!
