Description of problem:
Kickstart channels validation seems broken.

Version-Release number of selected component (if applicable):
spacewalk-java-2.0.2-46

How reproducible:
100%

Steps to Reproduce:
1. Sync Base channel only with kickstart trees to RH Sattelite.
     Ex: satellite-sync -c rhel-i386-server-6 --no-errata --no-packages

2. Create a kickstart ks_test.
    Systems-> Kicktart -> Profiles -> Create new Kickstart 

The following message will be displayed.

"The following packages are not available in any of the channels associated to this kickstart profile: pyOpenSSL, rhnlib, libxml2-python, libxml2, spacewalk-koan*. In order for all kickstart functionality to work correctly, these packages should be present in at least one channel associated to this profile."

that states that  packages pyOpenSSL, rhnlib, libxml2-python, libxml2, spacewalk-koan are missing.


3. Sync the RHN-Tools channel. This way spacewalk-koan package will get to the Satellite.
  Ex: satellite-sync -c rhn-tools-rhel-i386-server-6 
  
4. Go to kickstart ks_test.
     Systems-> Kickstart -> Profiles -> List profiles -> ks_test

Actual results: 
 The message is no longer displayed even though packages "pyOpenSSL, rhnlib, libxml2-python, libxml2" are still missing.


Additional info:

 According to the source code, if packages "pyOpenSSL, rhnlib, libxml2-python, libxml2" are available currently is tested only for RHEL[4,3,2] kickstarts.
