Comment 1 for bug 266230

We are having a similar issue. Running version 2.1.9 on RHEL4. We do not lose every email that is HTML. It is random and so far appears to be affecting only 1 user (although I suspect it occasionally happens to others as well). The message is successfully getting to mailman but is "disappearing" and here' s what we're seeing in the log:

Apr 05 23:56:35 2009 (4051) Uncaught runner exception: Expected list, got <type 'str'>
