Description of problem:
I've just installed Fedora7. After installation I updated the system using the
software updater - no problems in this step. After rebooting the computer I
tried to add a few packages using the "Add/remove software" tool, which resulted
in the error message shown in the attached file.

Version-Release number of selected component (if applicable):
Pirut version 1.3.9, release number 1.fc7

KDE version: 3.5.8-7.fc7 Fedora (same problem with GNOME)
Machine: i686

Installed: pirut.noarch 0:1.3.23-1.fc7
