The drawer controller's getInventoryName currently returns null but should return a string which can be translated into a user displayable name.

The controller has no UI. Is this for WAILA display purposes?

I think it's for something like an ME Interface/Storage Bus.

The ME Interface Panel lists all the names of the blocks that interfaces are attached to, and I remember seeing untranslated names in there.

When right clicking an EnderIO item conduit it will list the possible destination where items can be inserted.
This feature uses StatCollector.translateToLocal(inv.getInventoryName()) which will print "Chest" or "Furnace" for the vanilla tiles.

Quick test with AE2 shows it's using block names on the interface and not custom / inventory names.

Anyway fixed in 1.5.5 and tested with EnderIO. Controllers and drawers alike will support anvil renaming as well.
