Description of problem:
The 'inventory' report in the package 'spacewalk-reports' always returns a value of 1 or more 'errata_out_of_date' for every server. E.g. if a server has 5 outstanding errata, this report will show it having 6. If a server has 0 outstanding errata, this report will show it having 1. 

Version-Release number of selected component (if applicable):
spacewalk-reports-1.9.6-1.el5 (and possibly earlier).

How reproducible:
100% of the time. 

Steps to Reproduce:
1. Install spacewalk-reports. Make sure you have servers with and without outstanding errata. 
2. Run this command: /usr/bin/spacewalk-report inventory | awk -F',' '{print $3","$4","$11}'
3. The output of the above command will have '1' more 'errata_out_of_date' than what is displayed in the spacewalk web ui. 
  
Actual results:
The number of errata for every server has '1' added to the correct number. 

Expected results:
The number of errata for every server matches the count in the spacewalk web ui.
