libs/Sushi error with latest version

Not exactly sure when this gets triggered, but it happens pretty consistently with the latest version:

It's happening to me when I'm in the new vault area and the Recipe Rat vanishes from my bags. Might trigger when an object leaves your bags through non-standard methods.

I had this pop up today while flying in Icecrown, but I haven't been able to repro it.
