That app was installed on your device on day one, along with at least a few other installer apps (facebook, om weather, etc). You may have not noticed it until recently, but it's always been there. And if you re-flash your device, it will again be there, since it's part of the base image. Most of them are simple apps that do nothing but launch the app manager with a command line to install the app it's pointing to. Most of them were on the desktop by default, so a new owner could easily get a few widgets just by clicking them.

I monitor all my installs (and fs usage), and can tell you there are no apps (outside the initial set) that I didn't install myself. I have about 40 apps showing in the app manager uninstall list, and to the one I've asked for each one to be installed. If you're seeing something being installed on your device that you didn't ask for, then something you've put on it is causing this behavior. It's not part of the base image from Nokia or Maemo. If it were, everyone would be seeing it.
