Created attachment 4130 stracktrace Hi, From: https://bugs.launchpad.net/ubuntu/+source/thunar/+bug/847070 Thunar crashed trying to open a directory. StacktraceTop: thunar_file_is_ancestor (file=0xaaaaaaaaaaaaaaaa, ancestor=0x7fad20060360) at thunar-file.c:2172 thunar_tree_view_visible_func (model=<optimized out>, file=0x7fad20060360, user_data=<optimized out>) at thunar-tree-view.c:2196 thunar_tree_model_node_traverse_visible (node=0x7fad3c3cef60, user_data=<optimized out>) at thunar-tree-model.c:1777 g_node_traverse_pre_order (node=0x7fad3c3cef60, flags=G_TRAVERSE_ALL, func=0x7fad3bb827d0 <thunar_tree_model_node_traverse_visible>, data=0x7fad3c0abaa0) at /build/buildd/glib2.0-2.29.90/./glib/gnode.c:563 g_node_traverse_pre_order (node=<optimized out>, flags=G_TRAVERSE_ALL, func=0x7fad3bb827d0 <thunar_tree_model_node_traverse_visible>, data=0x7fad3c0abaa0) at /build/buildd/glib2.0-2.29.90/./glib/gnode.c:573 file=0xaaaaaaaaaaaaaaaa is a bit weird though...
I guess that view->current_directory is 0xaaaaaaaaaaaaaaaa because view has been freed somewhere else at the time of the call.
