Invalid messages and behaivor when opening Update Manager while upgrade operation is in progress

Binary package hint: update-manager

About minute ago I run onto possible bug that caused to appear:
1. Partial Upgrade dialog. I clicked NO.
2. Error message that Indexes were broken.

You might be able to reproduce this(-ese) bug(s) by performing following steps:
1. Open Ubuntu Software Center
2. Type in Search "Avant" ... then choose "Avant Window Navigator".
3. Start installing it.
4. Go to system menu and open "Update Manager".

After 4th step, you may experience same faulty behavior.
