This is not libvirtd's debug log unfortunately. You get that one by
enabling debug level output in /etc/libvirt/libvirtd.conf and looking
into syslog/the journal. But...

...although this uses a qemu in /usr/local/bin it still happens with the
one in /usr/bin as well so I can reproduce this here so no further info
required atm.

I'll try to have a look soonish...
