Bug Description
When logging out from the guest, occasionally the kvm will throw a segfault:
[46953.865611] kvm[2762]: segfault at 10 ip 00007f014ead854e sp 00007fff56385cf0 error 6 in libc2.15.
I am using the vmvga display driver. The guest was originally a VMware Fusion guest on a Mac. The guest is using the vmdk-disk image.
Some details about my system:
$ lsb_release -rd
