[Bug 2041831] Re: [SRU] Update-manager crashes when packages are de-selected with the mouse

[Tormod Volden]

I installed 1:24.04.9 from noble-proposed and clicked on the selection
tick markers to toggle them on and off repeatedly. I had 5-6 updates in
the list, one from a PPA. One was in a group, so I tested both clicking
the group tick marker and the package tick marker. I also clicked
multiple times quickly on the markers, since timing seemed to have a
role in the previous buggy versions. I was not able to make it crash.
With the previous versions it also didn't always crash immediately, but
it would always crash with the amount of clicking I had performed in
this test.

Title:
  [SRU] Update-manager crashes when packages are de-selected with the
  mouse

Status in update-manager package in Ubuntu:
  Fix Released
Status in update-manager source package in Noble:
  Fix Committed

Bug description:
  Impact
  ------

  Update-manager crashes if packages are deselected with a mouse click.
  If the keyboard spacebar is used instead (with focus on the package
  name or whole line, not the checkbox) it doesn't crash.

  Test case
  ---------

  0. Install the updated update-manager package.
  1. Start update-manager.
  2. Click various check boxes in the package list (i.e. unselect some packages with the mouse).

  Update-manager should not crash.

  Regression potential
  --------------------

  The user interface could become unresponsive.

  ---------
