I've had this problem when mailman was importing new lists (I had script running) and I wanted to access those lists. I am using sqlite as well.
I'm not sure this is our case, as we only have a few mailing lists and don't manually run any scripts. And yet this error comes up a lot (on the order of several times a day). I think it generally comes up when the user is clicking in the browser, getting a 500 error. After a reload or 3, it tends to go away, which is why I've been shamelessly ignoring this for months, but I can't get away with this anymore. :)
