This just happened to me also:
1. The upgrade manager suggested me to upgrade (from 7.04 to 7.10, see bug.png inside the attached tarball)
2. Then it shows an error (See see bugInfo.png inside the attached tarball) requesting to report the bug and provide some files, wich are attached as well within the tarball.
