Upgrade Tool crashed - from 7.04 to 7.10

Binary package hint: update-manager

I'm tryng to upgrade my 7.04 to 7.10, and didn't work

So I launch some // apt-get install -f // dpkg --reconfigure -a // apt-get upgrade // apt-get dist-upgrade // ...
and so on, till the system seems to be stable

then I launch adept again, then "Version Upgrade" button... don't know when, cause I worked on another machine but when I come back I find this traceback
