Description of problem:

- fresh F13 install (installed from NFS sources, as additional repos was specified fedora-updates and rpmfusion-{,non}free{,-updates} )

- run "Software Update" tool. It found 4 updates (gdisk from updates, dvd95/traverso/vobcopy from rpmfusion-free-updates)

- click "Install Updates", updates are downloaded, dependencies resolved etc.

- "Software signature is required" window appears with title "Do you trust the source of the package" for dvd95-1.6p0-2.fc13.i686 from rpmfusion-free-updates.

- "Authenticate:" "Authentication is required to consider a key used for signing packages as trusted" window appears, I enter root password and click "Authenticate".

- Ack "Do you recognise the user and thust this key" and appears error window "Could not update package", "Failed to process request." "More details:"

failed to install signature: Traceback (most recent call last):
  File "/usr/share/PackageKit/helpers/yum/yumBackend.py", line 2926, in install_signature
    self.yumbase.getKeyForPackage(pkg, askcb = lambda x, y, z: True)

- when I "yum update vobcopy gdisk", yum rightly prompt for and import GPG key for these (fedora-updates and rpmfusion-free-updates) repos and then update packages.

- subsequent "Software Update" tool run will rightly find outstanding two updates and install them.


Version-Release number of selected component (if applicable):
gnome-packagekit-2.30.3-1.fc13.i686
PackageKit-0.6.6-1.fc13.i686

Additional info:
PackageKit (or gnome-packagekit) probably expect, that GPG keys are already imported and crashes when not. YUM behaves correctly.
