Bug Description

TEST CASE:
1. open stock software-center
2. click on "installed" very quickly while the main page is still loading
3. verify that there is a traceback (note that this does not happen always, just most of the time)

I'll reopen this one as this crash seems to still be occurring in the latest version of Software Center in Precise, 5.2, as evidenced by the info on this page:

Mvo has a fix for this in place in lp:~mvo/software-center/lp959612 I've tested it and all seems well. It also seems to of resolved another issue of the installed page flicking back to the main lobby page when the lobby page finishes it's loading.

Hello Sasja, or anyone else affected,

Accepted software-center into precise-proposed. The package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!
