Description of problem:
Import of Rhel6 32/64bit to Satellite 5.4 fails

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

Satellite: 5.4.0 (embedded DB)
System: Rhel 5.6 x86_64(2.6.18-238.1.1.el5)
Failed ISO´s:
rhn-export-rhel-i386-6-20101207.0-01.iso
rhn-export-rhel-i386-6-20101207.0-02.iso
rhn-export-rhel-x86_64-6-20101207.0-01.iso
rhn-export-rhel-x86_64-6-20101207.0-02.iso

How reproducible:

Install an disconected Satellite 5.4.0 (with embedded DB) on a RedHat Enterprise Linux Server release 5.6 (Tikanga) an try to import Rhel 6 from an Mountpoint
 
Steps to Reproduce:
1. Satellite install: ./install.pl --disconnected --skip-selinux-test
ISO: satellite-embedded-oracle-5.4.0-20101025-rhel-5-x86_64.iso

2. Rhel iso copy:
Mount each iso and copy the whole thing:

#mount -o loop rhn-export-rhel-x86_64-6-20101207.0-01.iso /satcd/
#cp -ruv /satcd/* /mnt/rhnimport/rhel6/64bit/
#umount /satcd

#mount -o loop rhn-export-rhel-x86_64-6-20101207.0-02.iso /satcd/
#cp -ruv /satcd/* /mnt/rhnimport/rhel6/64bit/
#umount /satcd

3. Import a channel
#satellite-sync -c rhel-x86_64-client-6 --mount-point /mnt/rhnimport/rhel6/64bit/

Actual results:
Import Fails:
SYNC ERROR: unhandled exception occurred:

Additional info:
- Rhel5 import does work.
- Rhel6 32/64bit does not work
