system upgrade freezes when package upgrade fails

[Christian Kirbach]

I tried to upgrade from 15.04 to 15.10beta2 using "update-manager -c -d"

package "modemmanager" fails to update, and that in turn makes update-manager get stuck in the "update" phase indicated in the GUI.

Console log:

# update-manager -c -d

I know that a separate bug is open for the failing package.
This is about a different issue: upgrade-manager just froze with above python stack trace. The exception of a failing package upgrade should be handled. I admit that it should not happen.

It was failing when try to write the crash report regarding modemmanager and that was fixed in bug 1500450.
