software-properties-gtk goes beserk when downloading package information.

Same here.
I am running Jaunty 64bit.
My download speed is very low. I am speculating now but is there a chance that download speed causes this high CPU usage?

Thanks for your bugreport.

Could you please find the attached patch? I commited it to karmic, it shoudl fix the issue.
