bug with gtk_tree_item_remove_subtree

["Vianney Lecroart" <lecroart nevrax com>]

Hi,

I try to remove a subtree with the gtk_tree_item_remove_subtree() function.
It works fine when I don't select any child before removing the subtree.
The problem occurs when an item is selected in the subtree I want to remove.
In this case, the gtk remove function crashs.
It's a GTK_SELECTION_SINGLE tree so I try to gtk_tree_item_deselect the
selected item but it also crash.
Have you an idea of how to manage this without crash?
