b)
The package "gnome-vfs2" is a pre-requisite for this patch to work,
since the settings are (also) stored in the dconf schema.
c)
Also, a slightly unrelated change is the persistence of the values in
the "Network" control-panel.
Earlier, there was a timeout involved (of 3000 milliseconds), which
would trigger the saving of the values (for eg., "Collaboration Server"
field was persisted this way).
Now, the values are persisted SYNCHRONOUSLY, when the "tick"
toolbar-button is clicked (of course, all the changes are undone, if the
user instead decides to "Cancel changes").
d)
All the use-cases of the proxy, are working, as per the wiki page
