Title:
  "Provided by Ubuntu" leaks memory

Status in “software-center” package in Ubuntu:
  Fix Released
Status in “software-center” source package in Lucid:
  Fix Released

Bug description:
  Binary package hint: software-center

  This is observable with software center 2.0.3 and the trunk branch as
  well.

  TEST CASE:
  1) Launch software center and the system monitor to watch the memory consumption
  2) Click on the "Provided by Ubuntu" entry on the left, wait for the list to (re-)load
  3) Repeat step 2 several times.
  4) verify (using htop or top or gnome-system-monitor) that the memory increase considerable (~10mb or more)
  5) install software-center from lucid-proposed
  6) restart software-center and repeat step 2
  7) verify that the memory consumption does increase much less 

  Expected result: the memory consumption increases the first time, then
  remains stable.

  Current result: the memory consumption increases by approximately 12MB
  every time the list is re-loaded, and is never re-claimed. This
  eventually results in a very high memory consumption.
