Title:
  Software updater hangs/stops responding when clicking an update that
  has lots of version changes

Status in “update-manager” package in Ubuntu:
  New

Bug description:
  When viewing available updates, if I click on an update that has lots
  of version changes, then update manager will hang for a while/not
  respond. It will then come available again. I have noticed this a few
  times with raring

  This only happens when clicking updates with lots of version changes,
  it does not do it with others. I assume it's taking a while to
  handle/load the changes.

  This tends to happen with linux kernel updates as they contain a lot
  fo changes. Also Python3 today. I will leave a comment with the number
  of version changes that seem to cause the issue. Of course you will
  need to wait for a large update to reproduce.

  (I have an i7 processor so it's not slowing due to slow hardware)
