Description of problem:
I have org with 2 regular and 10 flex RHEL base entitlement. I have 2 regular systems registered and when I click on "2" in "Software Channel Entitlements" overview page, I'm getting ISE on network/systems/system_list/in_channel_family.pxt?cfam_id=1082.


Version-Release number of selected component (if applicable):
satellite-schema-5.4.0.9-1.el5sat


How reproducible:
For some reason, this appeared only 2-3 times, then after refresh correct list appeared.


Steps to Reproduce:
1. Register some clients (2 in my case) to RHEL channel
2. Overview -> Subscription Management -> Software Channel Entitlements=
     Red Hat Enterprise Linux (core server)
       Regular Consumed = 2
3. Click on that number "2"
   .../network/systems/system_list/in_channel_family.pxt?cfam_id=1082


Actual results:
ISE, 500


Expected results:
Should show these non-flex systems
