Build 13a4346 Stuck in unloading backpack forever

Build 13a4346. Linux curses never used debug default mods etc.
I have a situation where I was unloading a wielded backpack and it seems as if the game saved while this was happening.
Now I am stuck in the situation of “unloading 65%. Press . or 5 to interrupt”, but pressing . or 5 does nothing. I can ctrl-c out, but I cannot progress further in this game.
I have a copy of the save if anyone is interested, I can post a link. It loads into this situation.
Edit: It is doing something as the process is using 100% CPU, and it does respond to ctrl-c.
Edit: Tried loading it into 919d0fc but same…
