Dear Maintainer, I tried to get some more information from the dmesg lines.
It leads to the function "boxes_libvirt_broker_real_add_source_co", which is also written in the critical message before and unfortunately line numbers are for the generated c files from vala sources. There are several upstream bug reports that might be related (see at the bottom). Issue 603 notes that "~/.cache/libvirt" and/or "~/.config/libvirt" might be causing it and moving/renaming it could help. Kind regards, Bernhard # Minimal Bookworm/testing amd64 qemu VM 2022-11-28 apt update apt dist-upgrade apt install gdb gnome-boxes gnome-boxes-dbgsym https://wiki.debian.org/InterpretingKernelOutputAtProcessCrash error 4 == 0b00000100 --> 0: no page found, 0: read access, 1: user-mode access $ gdb -q (gdb) set width 0 (gdb) set pagination off (gdb) file gnome-boxes Reading symbols from gnome-boxes...
