I added some more information I extracted from gdb. Note the following: $ grep -c "visible = 1" model-nodes-array.txt 41
That is the same number as n_visible_rows. I'm not sure I understand 100% what gtk_file_system_model_sort() is trying to do, but it seems a bit fishy that r is incremented for each time in the loop, even if the node is not visible. My intuition is that r will end up being the total number of nodes, not the number of visible nodes, and that this might very well be larger than the number of visible nodes. (As I believe it in fact is in my crash.) But I'm not sure about the origin of the n_visible_rows; it comes from: n_visible_rows = node_get_tree_row (model, model->files->len - 1) + 1; so depending on how the model data structure should look, it might very well be correct. Also, I also noted that the call to this function reads: /* FIXME: improve */ gtk_file_system_model_sort (model); In my experience, finding a "FIXME" close to a place where a crash/assert happened is a prime suspect. This is probably how far I can take this; I don't have anymore gtk experience and not much more time debugging it either, unfortunately. If you need more info, I can probably re-create the situation quite easily, though.
