incus copy fails inside a container

Hi,

When running incus copy inside an incus container, a segfault occurs. I don't know if it's a packaging issue or an incus issue. Feel free to redirect upstream.

Steps to reproduce

incus launch images:debian/bookworm ctn
# in container "ctn"
# ... install incus
incus launch images:debian/bookworm a
incus copy a b
Error: Create instance from copy: Failed to run: rsync -a -HA --sparse --devices --delete --checksum --numeric-ids --xattrs --filter=-x security.selinux -q /var/lib/incus/storage-pools/default/containers/a/ /var/lib/incus/storage-pools/default/containers/b: signal: segmentation fault
