Math Error

Anyone who's been in the Z&A main store over the last year or two will have met Zanda at some point. He's our shop bot (or, more correctly, an avatar run by some software and with scripted agent status registered with Linden Lab). Chat near him shows up in his console and this includes object chatter and, of course, chatter on the debug channel. I'll often see errors thrown by people's attachments, the most common being AOs complaining about missing animations, the very common "stack-heap collision" and, on occasion, "too many listens".

And, now and again, there'll be a "Math Error". None have been quite as amusing as this one I just saw:

BOOBS FOR HUD: [script:mm_resize] Script run-time error
BOOBS FOR HUD: Math Error

I'm afraid to ask...
