Apparently, rg2 code relies on the fact that iter->user_data3 is a
pointer to the model. I don't know how this should be working globally
in this case of an iter generated from a signal, there is probably the
needs to intercept the data of the emitted signal to properly set
user_data3, because that's what seems to trigger your problem
(gtk_tree_model_get_values fired without a proper GtkTreeModel*
parameter); but I'll let that to the people who designed the
iter/user_data3 thing.

   Gtk-CRITICAL **:gtk_tree_model_get_value: assertion
`GTK_IS_TREE_MODEL (tree_model)' failed

In the meantime, replacing iter[0] by model.get_value(iter, 0)
workarounds the bug.
