Hmm. I'm pure perl there and I think I'm doing the right thing. Could be something hairy hurting gtk2-perl. Could be its xs/GtkTreeModel.xs gtk_tree_model_get() which does an EXTEND() which could be negative if there's more existing stack "items" than the intended" list of return values ("n_columns). SPAGAIN; EXTEND (SP, n_columns - items); SP += n_columns - items; PUTBACK; Does that sound likely? Is EXTEND() meant to do nothing on small negatives? Presumably it has done up to now. (I can understand disallowing wild negatives, but would it permit negatives which don't go below current "items"?) -- These prestigious wrought-iron security gates are bullet-proof, bomb-proof, and battering-ram resistant.

This has been attacked in Perl-Gtk2. I'll think about a recommends in my package when it's a released version, but anyone get()ting a full row from a 1-column tree model is affected.
