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

[Adam Bruce]

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)

Attatched is the version changes for the linux kernel.. a lot

I guess this would only really effect development users as final releases wouldn 't contain so many changes? So maybe a low priority, although it should be handled better in an ideal world
