I've been running into this very specific scenario that I can reliably reproduce:
- Have a .cbz file on a mounted SSD (notably NOT my primary SSD that houses the OS and home folder, this is an external one that is permanently connected and thus gets mounted on boot)
- Open it with the flatpak of evince (also called "Document Viewer" in Gnome)
I've got a reproducable .cbz file that I can share of that since then.
I ran journalctl -f > mycrashlog.txt in parallel in order to figure this one out, see attached txt file.
What I mostly arrived at was BUG: Bad page state in process fuse mainloop pfn:1e22e6
This is a kernel regression because I do not observe this behavior while booting into an LTS Kernel which I have installed since I use systemd-boot.
I'm not entirely sure where to report this now and what additional information to collect from there.
