Bug#606729: [CRASH] Uncaught exception ZeroDivisionError in Frontend/Gtk/GtkProgress.py:688

[Andrzej P]

Package: update-manager-gnome
Version: 0.200.4-1
Severity: normal
File: /usr/share/pyshared/UpdateManager/Frontend/Gtk/GtkProgress.py

   I see in the default Gnome notification area that there are
   updates.  I click on the icon and I am asked for my root password
   and 'update-manager' launches.  I see the list of updates and
   select "Install Updates".  Immediately a dialog comes up saying
   that a "fatal error" has been encountered.  The update itself
   appears to take place regardless since 'dpkg' and other related
   processes are visible in 'top'.  Packages appear to have been
   updated to the new versions.

   When I launch 'update-manager' from the command line instead, the
   single line output to the terminal is:

   W: Unbalanced action groups, expect badness

   Update Manager remains unresponsive.  This has happened every
   single time on this fresh install using Squeeze Debian-Installer Beta1.
