Thanks for taking your time to report this issue and help making Ubuntu better.
I have the same weird issue with update-manager 1:0.186.1 on Ubuntu 13.04. According to the updates indicator, 19 updates are available, though only five of them are listed when I open the update-manager. As for you, I get the complete list when running `apt-get dist-upgrade`.
