1. This was an "Erase disk and install Ubuntu" installation from a USB stick, with "Install updates" and "Install this third-party software" both checked.
2. While the problem was happening:
- some applications in Main showed up in USC with icons
- some applications in Main, such as Thunderbird and Pidgin, showed up without icons
- the screen for anything in Main said "Available from the 'main' source ( Use This Source)"
- "Use This Source" triggered an apport dialog
- apport refused to report a bug as described.
3. The problem went away completely as soon as Ivanka chose "Use This Source" for an application in Universe. (So I guess "sudo apt-get update" would have fixed it too.)
