Was using the Quick/Smart Deposit inventory features from Quark when I ran into this error.

It only seems to happen when I am in range of any Actually Additions blocks, regardless of if they have an inventory or not.

You'd do me a huge favor if you compiled the mod from github and then checked with Quark again.
However, if you don't know how to or don't want to, just wait until the next update is released :)

There.
Now this should be proper.

Awesome! I would certainly not mind checking it for you, but I have no idea how to compile it from GitHub.
