[Gluster-devel] Segmentation fault while running the client

Hello everyone, 
	I'm trying to configure a cluster file system with Gluster, but when I
try to mount the file system I get a segmentation fault error.  

My configuration at the moment includes one server and one client (but
in the future it'll be multiple servers and multiple clients); here it
is: 

========================= SERVER =====================================
### Export volume "brick" with the contents of "/home/export" directory.
volume brick
  type protocol/client
  type storage/posix                                      
  option directory /mnt/localspace/gluster/fs      
end-volume

volume brick-ns
  type protocol/client
  type storage/posix                                      
  option directory /mnt/localspace/gluster/ns 
end-volume

### Add network serving capability to above brick.
volume server
  type protocol/server
  option transport-type tcp/server     # For TCP/IP transport
  option client-volume-filename /etc/glusterfs/glusterfs-client.vol
  subvolumes brick brick-ns
  option auth.ip.brick.allow 10.78.36.* # Allow access to "brick" volume
end-volume

========================= CLIENT =====================================
### File: /etc/glusterfs-client.vol - GlusterFS Client Volume
Specification
### Add client feature and attach to remote subvolume of server1

volume client3
  type protocol/client
  option transport-type tcp/client     # for TCP/IP transport
  option remote-host 10.78.36.204      # IP address of the remote brick
  option remote-subvolume brick        # name of the remote volume
end-volume

volume globalns
    option transport-type tcp/client
    option remote-host 10.78.36.204
    option remote-subvolume brick-ns
end-volume

### Add unify feature to cluster "server1" and "server2". Associate an
### appropriate scheduler that matches your I/O demand.
volume unify
  type cluster/unify
  subvolumes client3
  option namespace globalns
  ### ** Round Robin (RR) Scheduler **
  option scheduler rr
  option rr.limits.min-free-disk 4GB 
  option rr.refresh-interval 10  
end-volume
=============================================================

Am I doing any silly error? 
This is what I get from running gdb:
 
Starting program: /usr/local/test/sbin/glusterfs --no-daemon
--log-file=/dev/stdout --log-level=DEBUG
--spec-file=/etc/glusterfs/glusterfs-client.vol /mnt/space/
