upgrade tool crashed

Binary package hint: update-manager

When upgrading from kubuntu feisty to gutsy during packages installation :
I had a problem with libkipi0 that cannot be installed.
So gwenview has unresolved dependencies.
I had a question about replacing /etc/modprobe/blackist
and just after my click on replace I had a crash :
