Description of problem:
When using the installer, should a disk read error occur when attempting to
install a package, a dialog is displayed explaining the circumstances to
the user. (The dialog correctly suggesting possibility of bad media, dirty
CD, etc.) A single option to acknowledge and retry is presented. 

However, the CD cannot be ejected for cleaning / inspection by the user, as
it is mounted. Hence, the user cannot likely remedy the failure situation,
and is forced to restart the installation process completely.

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


How reproducible:
Didn't try

Steps to Reproduce:
1. Dirty CD 2 of your disc set. (Disc 1 may also be dirtied, but for ease
of reproduction it is better to dirty Disc 1.)
2. Perform a full install. (Which guarantees the dirty spot should get
hit.)
3. Attempt to eject the CD to clean it when a read error is reported.
	

Actual Results:  The CD is currently mounted and cannot be ejected.

Expected Results:  The CD should be umounted before the error dialog is
raised. This will allow the user to clean / replace the CD before retrying.
After the dialog is dismissed the CD should be remounted.

Additional info:

This bug is similar to 35081 and 25724. However, the request is _not_ for a
feature enhancement to allow a package to be skipped. Instead the request
is for the installer to have the behaviour one would likely expect -- when
reporting a possibly dirty CD, the user should have the opportunity to
clean the problem CD before retrying.
