error when stack size changes

[Lugalbanda]

Seems to happen when the number of items in a stack changes: using a potion, turning in a daily writ, or simply splitting a stack, etc. Does not happen every time a stack changes, but more often than not, and does not seem to happen at any other time. I didn't notice anything that would help narrow things down to a particular addon, but it's unlikely that I can maintain reasonable focus after ~reading 10% of it. ;P Maybe Inventory Insight, because it's always monitoring inventory changes. Oh, and I see gamepad-specific stuff there, but it happens even with gamepad mode completely disabled, even with gamepad unplugged. Hmm. Stopped happening when I /reloadui with gamepad mode disabled and gamepad unplugged, even when I reactivated gameapad and used gamepad to split a few stacks. It's been happening for several days though, so I doubt that I've permanently fixed it.
