Hi again!
i haven't looked at your patches, but for the sake of simplicity i have
omitted the warning that an abstraction must not kill itself.
e.g. if you trigger the "menuclose" from within the abstraction (or the
trigger "goes through" your abstraction), this will crash Pd.
it is both a bug in your patch ("suicide" will kill you) and a bug in Pd
(even though it is a bug in the patch, Pd should never just crash)
