Description of problem:
Upgrading from RedHat 7.2 to Phoebe dies with a dialog box that says "disk
space" at the top, has a light bulb and "OK" button, but no text whatsoever.
The filesystem is 6 GB in size, with about 4 GB free, and the upgrade is
approximately 4.5 GB in size -- i.e. too much as addition, but should fit on the
filesystem when old files are removed.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
*** Bug 80720 has been marked as a duplicate of this bug. ***
Should be fixed in rpm > 4.2-0.50
This is fixed in Phoebe public beta 2 (dup of a few others).
