Unfortunately there's no indication which version of libvirt you're using, hopefully it's the one in sid?Thanks, I am using 11.3.0-3+b1 of libvirt-daemon.This looks odd: there is no 11.3.0-3+b1 in Debian. Have you rebuilt libvirt locally? Perhaps including custom changes?This is an issue in libvirt, not qemu, - it is the one who segfaults, and it definitely should not crash.Agreed. Can you try installing libvirt 11.6.0-1 from experimental and see whether the issue still reproduces? Alternatively, 11.7.0-1 should come to unstable in a week or so. Since there's a non-zero chance that the issue has already been identified and addressed upstream, I'm not too eager to start debugging this very second :)
For reasons I don't quite understand, the issue appears to have solved itself. Just for testing purposes, I re-installed qemu 10.1.0+ds-1 and now the segfaults upon connecting to qemu://system with virt-manager do not happen anymore.

I can assist further in debugging if desired. Otherwise the bug can be closed.
Kind regards and thanks for your time, David
