Hi,
I'm seeing a crash in libvirt when trying to list all domains using virsh.
Here's the backtrace:

=====================
This is with the newest version from git, pulled about 30 minutes ago.
This happens when I try to start up one of the defined domains using either
libvirt or virsh and then try to list all the defined domains in virsh using
list --all.
The attempt to start one of the domains already fails with the following
output:
=====================
virsh # start testserver-a
error: Failed to start domain testserver-a
error: internal error process exited while connecting to monitor:

=====================
This happens with all the domains I have currently defined.
Calling list --all before that produces no problems.
Calling list --all after that always produces said crash.
qemu is qemu-kvm 0.12.4, built from sources.
The host system is a Fedora 12 install.
