Bug#622701: update-manager-gnome: Downloading list of changes failed

[Dominique Brazziel]

Package: update-manager-gnome
Version: 0.200.5-1
Severity: important

    I've been getting this message consistently recently, whereas
before it was occurring only for some packages in the update list.
Being able to view what bugs were fixed in a package update is one of 
the best features of update-manager, now the changelog viewer seems to 
fail for every package in the list.  

    The message is issued from 'Frontend/Gtk/ui.py'.  I will
try to turn on debug logging for the DistSpecific ChangelogHandler
and see if I can see where exactly things are failing.
