Been getting a lua error since the last patch I think:

 Just had this start happening to me, no occurrences prior to today.  Usually behaves itself the first time or few after a fresh log-in or /reloadui but not always (so it seems unlikely it's a specific problem item, though not impossible).  Including my error trace as well, since the dump at the end's different.
