partners refreshes too often

[Kiwinote]

Binary package hint: software-center

s-c 1.1.26, partners enabled, acroread installed.

Browse to the partners list view and remove acroread from within the list view. Note that just after removal the screen refreshes (ie blanks white) and then about 5 seconds later the screen refreshes a further 5 times. This sometimes happens during the removal as well.

TEST CASE:
1. use lucid
2. open software-center
3. select a application (like accessories, 7zip) and click "more info"
4. click on install button in the details view
5, wait until it finished, wait about 10s more and verify it flickering a couple of times
6. install software-center from lucid-prposed
7. repeat step 2-5
8. verify that after the install finished it flickers at most once (after ~10s)

I can reliably reproduce. The same also happens *after* installing acroread from the partners source.

This also happens with other views (e.g. "Installed Software"). The flickering is less obvious, but the refresh happens in the same fashion (5 times in a row approximately 5 seconds after the initial refresh).

An obvious symptom is that when the refresh happens, the first item in the list is selected with a delay, so the row expands (to show the "More Info" and "Install"/"Remove" buttons). When there is no flickering, the first item seems to be unselected and selected again 5 times in a row.

The linked branch implements an incomplete fix.
By making sure the APT cache is not re-opened many times in a row, the view refresh (and thus the screen flickering) is reduced to only one occurrence too many.

The linked branch now contains a complete fix ready for review.

Accepted software-center into lucid-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!
