this is actually a bug in update-notifier, not update-manager.
attached is an svg version of the "updates-notifier" image that could be used by the application (currently the only version icon is located at /usr/share/icons/hicolor/16x16/apps/updates-notifier.png). Not very detailed, but at least it scales :)
Perhaps the tango project has an icon that would do the job better?
