Thanks Nick for the tip; I've recently learned about debug-on-entry, which I attempted to use to no avail last night, but the functions listed in the info manual you cited are useful. Following them I have found that the problem seems to be a conflict bewteen Org-Contacts and Helm; loading without helm enabled fixes the problem. Unfortunately, this seems like a lose-lose tradeoff to disable helm or go without mailing list functionality. I'm open to any suggestions, now that I know that a Helm conflict is apparently causing the listp error.
