Bug Description

I am on Ubuntu12.04 64bit updated to 2.3.2012.

The Software center crashed on the search term"python".

This crash occurs only intermittently under certain conditions when an image download fails. As such, this error can't be reliably reproduced. However, to test, you can fully exercise this code by clearing the downloaded icon cache and then reloading them per the following steps:
1. Install the version of software-center in precise-proposed.
2. With Software Center not running, execute the following in a terminal:

    $ cd ~/.cache/software-center/icons
    $ rm *

3. Launch Software Center and navigate to "All Software" -> "For Purchase"
4. Verify that as you scroll the list the application icons are loaded in the view.

Very low. If a regression were to occur, it would manifest as "generic" icons appearing in the list views or the details view.

Open software center, search dropbox, click install, then it crashed
