gpk-update-viewer is installed by default on openSUSE GNOME systems and
periodically shows notifications about package updates. Unfortunately, it does
have a tons of weird UI bugs that not only make the software feel unfinished
but also make the desktop itself feel unpolished.

One of these issues is that gpk-update-viewer will create notifications
periodically about updates being available. However, it will also create these
notifications despite the fact that no actual updates are available: You click
the notification, the gpk-update-viewer main window opens and it tells you
there are no updates.

This is not appropriate behavior for a default system component that users
periodically have to interact with and which can't be uninstalled without also
uninstalling important GNOME patterns.

Please update the tool to avoid sending useless notifications.
