It says simply and clearly what has happened. It denotes the relevant context (del) in which it happened. The reader can then decide to find out why that decision may have been made. Why not MRAB's? ("Cannot propagate exception...") While better than "Unpropagatable exception" and "unraisable" and "unreraisable", it has the same flaw that I think underlies Antoine's concerns: it suggests the reason there's an error printed instead of further propagation is a property of the exception. It doesn't say it outright, but as an outsider that is definitely what I would at first infer. So: a small +0.1 for "Cannot propagate exception..." And: a big +2 for "Exception in del caught and not propagated:". Well, my suggestion was more about eliminating the adjective+noun form; it seemed it just wasn't possible to cram the desired meaning into a single word, so it was better not to try!
