After converting all my raw images to qcow2 the host no longer segfaults, but I still get a corrupted btrfs filesystem. Please have a look at this new image at http://home.react.nl/~sjon/bug-reports/btrfs/btrfs-corrupt.qcow2.gz (16 KiB) It contains a 20 GiB disk with 1 partition that btrfsck (again) has no problems with, but I cannot mount it.
