Crash with 0.44.12-r1 and 6.54 on linux

[carewolf]

I get a reproducible crash with a backtrace that looks something like:

I got it with twbt 6.53 and tried upgrading to 6.54 but it didn't help

So.. how do I reproduce it?

I seem to reliably be able to reproduce this (or something similar, haven't checked the stacktrace) with the latest GemSet. World starts loading but at some point I get garbled text and the game freezes.
