Description of problem:
When you forcibly expire identity certificate (registering a system and forwarding date by 25+ years) and try opening subscription-manager-gui from the client machine Applications->System Tools->"RedHat Subscription Manager" (not through the CLI) the GUI does not open

Version-Release number of selected component (if applicable):
# rpm -qa | egrep "subscription-manager|python-rhsm"
python-rhsm-1.8.9-1.git.7.214419e.el5
subscription-manager-migration-data-1.11.2.7-1.git.0.1dfd00e.el5
subscription-manager-gui-1.8.6-1.git.7.96019b0.el5
subscription-manager-firstboot-1.8.6-1.git.7.96019b0.el5
subscription-manager-migration-1.8.6-1.git.7.96019b0.el5
subscription-manager-1.8.6-1.git.7.96019b0.el5


How reproducible:
Always

Steps to Reproduce:
1. Register Client to Candlepin
2. Forward date on client and candlepin by 25+years
3. Try opening GUI from client 
   Applications->System Tools->"RedHat Subscription Manager"
