TreeView works bad

[Martin Klaffenboeck <martin klaffenboeck gmx at>]

Hello,

My application crashes when I do the following:

1. Filling the treestore in a callback of a search.
2. Opening a subfolder in the treeview.
3. Select an Item in the subfolder, which does a callback with the 
TreeSelection. The callback doesn't do anything with the TreeModel.
4. Closing the Subfolder.

The last messages I get:

(gports:38264): Gtk-CRITICAL **: file gtktreestore.c: line 635 
(gtk_tree_store_get_value): assertion `iter->stamp == GTK_TREE_STORE 
(tree_model)->stamp' failed

 (gports:38264): GLib-GObject-WARNING **: can't peek value table for 
type `<invalid>' which is not currently referenced

gdb aborts with:
