--- Comment #42 from Tim Steinberger <tste...@protonmail.com> --- I found this bug after googling what seemed to be the error message most likely to cause the crash. As this gave the exact same behavior I assumed this was what was causing it. Here is the log from the command line if I start discover from there, maybe I missed something obvious. Icon theme "ubuntu-mono-dark" not found. Icon theme "Mint-X" not found. Icon theme "elementary" not found. Icon theme "gnome" not found.
