[Bug 1139803] [NEW] Software updater hangs/stops responding when clicking an update that has lots of version changes

[Adam Bruce]

Public bug reported:

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)
