You are the first after a long time who bothered to use a debugger himself before posting to the list and included the actual code, the actual error messages and noted the place where it crashes (sort of) in the post. This is not a reason for an apology, but for opening a bottle of champagne...

Evidently, the tree model does not exist any more here (the other likely possibility would be passing a wrong pointer as the model, but I just happen to know). And that's because here > g_object_unref( part_model ); you release your reference to it. The only remaining reference is that owned by the treeview, which is released when the treeview is closed (destroyed) and then the model goes poof because it is not used by anything (more precisely, nothing claims any use of it -- you still think you use it, but since you do not own any reference, nothing knows you want to use it). Keep your reference until you are done with the model (and don't release references more times than you took them). Unreferencing the model immediately after gtk_tree_view_set_model() is convenient when you want the model to be destroyed together with the view and/or when a different model is set -- but that's the opposite of what you want. Also, clearing the model and filling it with something completely different will not save much. Creating a new model, filling it, calling gtk_tree_view_set_model() and unreferencing the new model can be even more efficient.
