up2date multiple problems in FC4

[Glenn Story]

up2date is misbaving in multiple ways on an FC4 fresh install:

1.  The icon that shows whether there are unprocessed updates shows a
blue checkbox, even though there are updates I need.

2.  When running up2date, every file complains that there is no GPG signature.

3.  The command "up2date --get-source kernel" blows up with a python
stack trace:

4.  The "total progress" progress bar is always at 100% during download.
