Description of problem:
 "Segmentation fault" when use virsh list with vdsm

Version-Release number of selected component (if applicable):
# rpm -qa libvirt kernel qemu-kvm-rhev vdsm spice-server
kernel-2.6.32-280.el6.x86_64
spice-server-0.10.1-10.el6.x86_64
qemu-kvm-rhev-0.12.1.2-2.297.el6_3.x86_64
libvirt-0.9.13-3.el6.x86_64
vdsm-4.9.6-21.0.el6_3.x86_64

How reproducible:
100%

Steps to Reproduce:
1. prepare a host registering to rhevm
2. Install a vm use rhevm in the host
3. Set up a Certificate Authority (CA)

 1) # certtool --generate-privkey > cakey.pem

 2) self-sign cakey.pem by creating a file with the signature details called
ca.info containing:

cn = 10.66.93.59
ca
cert_signing_key

 3) # certtool --generate-self-signed --load-privkey cakey.pem --template
ca.info --outfile cacert.pem

4. Create vdsm certificates

 1) certtool --generate-privkey > vdsmkey.pem

 2) sign that key with the CA's private key by first creating a template file
called vdsm.info

organization = Red Hat
cn = 10.66.93.59
tls_www_server
encryption_key
signing_key

 3) # certtool --generate-certificate --load-privkey vdsmkey.pem
--load-ca-certificate cacert.pem --load-ca-privkey cakey.pem --template
vdsm.info --outfile vdsmcert.pem

5. # cat /etc/libvirt/qemu.conf

dynamic_ownership=0 # by vdsm
spice_tls=1 # by vdsm
spice_tls_x509_cert_dir="/etc/pki/vdsm/libvirt-spice" # by vdsm


6. # cat /etc/sysconfig/libvirtd

LIBVIRTD_ARGS=--listen # by vdsm
DAEMON_COREFILE_LIMIT=unlimited # by vdsm

7.#cat /etc/libvirt/libvirtd.conf

listen_addr="0.0.0.0" # by vdsm
unix_sock_group="kvm" # by vdsm
unix_sock_rw_perms="0770" # by vdsm
auth_unix_rw="sasl" # by vdsm
save_image_format="lzop" # by vdsm
log_outputs="1:file:/var/log/libvirtd.log" # by vdsm
log_filters="1:libvirt 3:event 3:json 1:util 1:qemu" # by vdsm
ca_file="/etc/pki/vdsm/certs/cacert.pem" # by vdsm
cert_file="/etc/pki/vdsm/certs/vdsmcert.pem" # by vdsm
key_file="/etc/pki/vdsm/keys/vdsmkey.pem" # by vdsm

(Note: make sure all the *.pem files should be existed in the corresponding dirs, refer to the setup steps to generate the pem file)

8. # initctl restart libvirtd

9. # echo redhat | saslpasswd2 -p -a libvirt test

10. # virsh list --all
or other virsh commands

Actual results:
Segmentation fault

Expect result:
Give "Please enter your authentication name:
Please enter your password: "
if input right name and password, virsh commands will work well.

additional :
libvirt-0.9.10-21.el6_3.3 works well, so should be set as regression.

and I cat the debug info in libvirtd.log like:
# cat /var/log/libvirtd.log
