Title:
  update-manager grabs major share of CPU&RAM when browsing list items

Status in update-manager package in Ubuntu:
  Confirmed

Bug description:
  The moment e.g. "Header files to the Linux kernel version 3.2.0" or
  "Linux kernel headers vor version 3.2.0 on 32 bit x86 SMP" (-44
  thereof, i.e. between second and subsequent kernel-related entries
  from the top today) is highlighted, update-manager 1:0.156.14.11 on
  Ubuntu 12.04.2 LTS deselects the item, reproducibly grabs 100% CPU,
  becomes barely responsive for minutes (on a 2.66 MHz Dual Core) and
  starts leaking memory (process had to be user-terminated when taking
  more than 30% of 2 GB). Neither delays nor excessive RAM consumption
  occur when moving the selection within the lower, non-kernel items of
  the update list.
