update-apt-xapian-index crashed with UnpicklingError in /usr/share/software-center/softwarecenter/db/update.py: invalid load key, '9'.

[Pedro Nariyoshi]

Binary package hint: apt-xapian-index

Everytime I log in, I receive the message that this and ubuntu software-center have crashed.

I've reinstalled both of them, but it doesn't seem to help
