[ubuntu-mono] [Bug 705558] Re: assertion `gtk_tree_model_iter_next (tree_view->priv->model, &iter)' failed.

[Bryan Larsen]

I had to log out and log in again to be able to restart tomboy.   (It
complained that it was already running, but ps didn't show a process).

I restarted, and none of my notes had synced over except perhaps for the
conflict I reported, which was with the "Start Here" note.

I did another synchronization, and it worked fine.

  Crash happened on first sync with Ubuntu One server.   I resolved one
  conflict, and then *boom*

  There is a disparity between the internal view of the GtkTreeView,
  and the GtkTreeModel.  This generally means that the model has changed
  without letting the view know.  Any display from now on is likely to
  be incorrect.
