Bug 120514

Description of problem:
If I use "Add or Remove Packages" - redhat-config-packages to install
some software, and I need to change CDs, after changing CDs "Add or
Remove Packages" bails out. 
 
(If I after that re-run "Add or Remove Packages" and choose that same
package again, this time with the right CD in the drive from the
start, it works.) 
 
It seems that it could possibly be related to me having two
CD/DVD-drives in the system.

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


How reproducible:
Always

Steps to Reproduce:
1. Have the wrong CD in the drive.
2. Run redhat-config-packages
3. Choose to install something.
4. Insert the correct CD when prompted.

Actual Results:  It pops up an error dialog saying "Error installing
packages There was an error installing packages. Exiting."

And in the terminal it prints (for example): 
 
"The file /mnt/cdrom/RedHat/RPMS/units-1.80-8.i386.rpm cannot be
opened. This is due to a missing file, a bad package, or bad media.
Press <return> to try again." 
 
It has the RHEL CD mounted on /mnt/cdrom1 and another CD in my other
drive mounted on /mnt/cdrom. Before running redhat-config-packages no
CDs were mounted.

If I rerun redhat-config-packages after this happens it will install
the package.

Expected Results:  It should have installed the package at
/mnt/cdrom1/RedHat/RPMS/units-1.80-8.i386.rpm.

Additional info:

I have noticed that if I do it "the same way but opposite", ie have
the unrelated CD in cdrom1 and the RHEL CDs in cdrom, it seems to work
after changing CDs. So it seems only to happen when the second CDROM
drive is used.
