Public bug reported: I am on Ubuntu12.04 64bit updated to 7.4.2012.
On this platform I am using qemu-kvm1.0 with virt-manager(?->latest). I have had runned a Ubuntu12.04 guest in this configuration. On newstart sequence to finishing updates of the guest(new kernel verison) the guest vm crashed. A .crash file was gathered in /var/crash/ for this, but apport failed to report it and crashed itself: https://bugs.launchpad.net/ubuntu/+source/apport/+bug/975832 The .crash file of the qemu-kvm issue is above 600MB of size, which may be the cause for apport failing.
