It looks like something is setting your `tabulated-list-use-header-line' variable to nil *between* the buffer initialization and the list printing. So the `tabulated-list--header-string' variable doesn't get set (it's normally set during buffer initialization), but when it's time to print, the variable is expected to be a string. I think that's a bug in tabulated-list-mode (which I'll try to get fixed now), but do you have any hooks or advices that may be causing that?
