[Bug 945536] Re: Excruciatingly slow package list onscreen update

[Brian Murray]

** Description changed:

  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: 
+ To reproduce:
  - with some updates waiting
  - open update-manager
+ - click "Description of update" expander
  - 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
