Description of problem:
I have correctly running cluster. I change cluster.conf on one of the nodes with non-valid xml. I run ccs_tool to update this config version to all the nodes which it correctly does. Running "clustat" after that on any of the nodes leads to Segmentation Fault.

Version-Release number of selected component (if applicable):
This is RHEL5.9-candidate-20120813, rgmanager-2.0.52-34, running on ia64.

How reproducible:
Always.

Steps to Reproduce:
1. Have three node cluster on rhel5.9 ia64.
2. Modify /etc/cluster/cluster.conf on any of the nodes as follows (add <a> tag and increase config_version):
<?xml version="1.0"?>
<a>
    <cluster name="a_cluster" config_version="303">
	...
    </cluster>
</a>

3. run: ccs_tool update /etc/cluster/cluster.conf
4. check that all nodes report that the config has been updated correctly.
5. run: clustat
  
Actual results:
Segmentation Fault (core dumped)

Expected results:
Cluster status shown.
