[1.7b6] "Use item" menu is broken

[pfhyyhtsche]

Using anything from inventory with the 'Use items' (default key 'u') command doesn't work, including rod of recall and inscriptions, throws a lua error. Opening the regular inventory and using the item from there works as normal. Probably Swift Hands fault, not that I had it, but iirc it's broken inventory before and it got changed, sooooo.
