Sample cluster.conf file that causes the bug.

Description of problem:

When trying to setup redundant ring protocol by setting 'rrp_mode' to 'passive' or 'active' and then defining two <interface ...> elements, the cluster fails to start with error 8.

Version-Release number of selected component (if applicable):

cman-3.0.14-1.fc13.x86_64
corosync-1.2.7-1.fc13.x86_64

How reproducible:

100%

Steps to Reproduce:
1. Set '<totem...>'s 'rrp_mode' to 'active' or 'passive'.
2. Define two '<interface ...>' elements
3. Start cman
  
Actual results:

Results are the same for either 'passive' or 'active':
