Update-manager crash at "Cleaning Up"

[ddcc]

While updating from Gutsy to Hardy, the update-manager crashed right before "Cleaning up...", though after rebooting the system seems to be upgraded to Hardy and working ok. I would like to know is there any way to manually do the clean up though?

try

sudo apt-get clean

I've managed to "fix" it by using sudo apt-get clean, as well as by modifying the python source code (in a local directory) to jump straight to the cleanup function.
