Summary: Uncaught runner exception: iteration over non-sequence

Initial Comment:
I don't normally check /var/log/mailman/error as long as everything seems to be working, but today I noticed loads of errors like this one:

I can provide more samples if necessary. I have searched the tracker for other reports like this, but haven't seen any ...

There is a problem with the message. Try running bin/show_qfiles or if
that doesn't work, bin/dumpdb on one or more of the shunted files (e.g.
qfiles/shunt/1167220351.925714+8af35bc9b49ca21d542d7fac99bdb87a688619ef.pck).

In any case, can you send me this file or attach it to this report.
