Calling gtk_dialog_run() out of many sorts of callback 
a bit dangerous. (GtkButton::clicked and GtkMenuItem::activate
are pretty safe)

I think the problem is that your modal dialog is eating the button
release, so GTK+ gets confused. You'll have better luck if you,
say add an idle function (g_idle_add()) that does that action.

That being said, GtkTreeView could probably do better, so it 
wouldn't hurt to file a bug. (bugzilla.gnome.org, see instructions
in the GTK+ README.)
