[Bug 979994] [NEW] After check for updates complete, packages in list dissappear and reappear (sometimes one by one)

[Greg Auger]

Public bug reported:

Steps to reproduce:

1. Get Update Manager to a state when there are updates available, and visible in the list
2. Press Check

Expected result: previous packages stay on list, new available packages
are added to the list, any now unavailable packages are removed from the
list.

Actual result: entire list disappears and is slowly repopulated (even if
nothing has changed)
