Watchdog logs highlight a compatibility problem with Admin Menu and Ubercart?

Hello.

Today I noticed for the first time what I consider a weird behaviour in the Watchdog Recent logs in a Drupal 5.20 installation.
It reports seven "Page not found" warnings:
1. Message: "/sites/all/modules/openads/openads.js" (Note: I do not have Openads installed).
2. Message: "/sites/all/modules/panels/js/panels.js" (Note: I do not have Panels installed).
3. Message: "files/ubertheme_favicon.ico"
4. Message: "files/pixture_logo.png"
5. Message: "sites/all/modules/google_analytics/googleanalytics.js" (Note: I do not have Panels installed)
6. Message: "files/css/749bb2434901831ecd5d4b37499b2fc7.css"
7. Message: "sites/all/modules/fivestar/js/fivestar.js"

All the Page not found warnings arise when I visit the page "/admin/store/settings/store/edit/report".
I have Ubercart 5.x-1.8 and The Administration menu module installed.

Does anybody have any idea? Has my system been "attacked"?

Thank you ever so much!
