Bug#816246: boinc-manager:task tab in advanced view does not update properly -> last active task does not update automatically, regardless of sort order

[vic_dev]

Package: boinc-manager
Version: 7.4.23+dfsg-1

The task tab in the advanced view does not update properly, the last 
active task does not update automatically, instead it displays the same 
thing all the time until user interacts with the task list. (Last active 
task = the active task at the bottom of the list, regardless of sort order.)

The last active task only updates when I click on any task in the list, 
or when the sort order is changed, or when switching away from the task 
tab then back again.  Changing the sort order does not change this, it 
just moves the non-updating behavior to whatever task ends up at the 
bottom of the list.

This behavior is the same on two computers in either the Gnome or Xfce 
desktops.  Each computer has an AMD Phenom II X4 processor, with an 
Radeon 5850 graphics card, using both CPU and GPU to crunch Seti at Home 
workunits (using OpenCL).

Noticed this behavior a long time ago, has been an issue for several years.
