[Bug 945536] [NEW] Excrutiatinling slow package list onscreen update

[Nick Barcet]

Public bug reported:

Update-manager seem to take something like 0.3s to refresh each package
in the list (when there is 343 updates, took about 3 min to refresh the
whole list).

To reproduce: 
- with some updates waiting
- open update-manager
- click on the check button
- wait for the update progress window to close
-> Watch the onscreen package list being slowly updated one package after the other.

Possible cause: extraneous list refresh function being called after each
addition/removal to the list
