lat crashes when deleting a [connected] server

[Paul Manners]

Binary package hint: lat

In hardy, I start lat and connect to a local ldap server on my network. Selecting this new server entry and pressing the delete button on the toolbar causes the program to crash and the following message:

Exception in Gtk# callback delegate
  Note: Applications can use GLib.ExceptionManager.UnhandledException to handle the exception.
