WoWInterface - [10 rev 1] - suddenly, stacking error!

For some reason, this error suddenly started stacking.

What was I doing? Just dancing at Club Trix with my DJ character Pixiz. Was dancing for hours before the error started stacking. Best I can think of is it started when I "/sexy"d a target. It's the only thing I can think of as even a possible trigger.
