Upcoming FC1 desktop updates

[Warren Togami <wtogami@xxxxxxxxxx>]

In about a week I intend on issuing updates for FC1 control-center, 
gnome-vfs2 and htmlview that backport the Preferred Application fixes 
from FC2.  These fixes were extremely simple and very well tested, and 
corrects the very common problem of user applications not using the 
chosen browser or mail client when URLs are clicked.  Specifically these 
changes I want to backport:

* gnome-vfs2: Default gconf schema that defines the "about:" type.
* gnome-vfs2: Default gconf schema pointing to mozilla, so default 
Desktop is guaranteed to run a browser that is installed.
* control-center: Preferred Application chooser sets http, https, about, 
and unknown gconf keys.
* control-center: Preferred Application chooser shows only installed 
applications, rather than a hard coded list.  (Note that I need help 
verifying that there were no end-user visible string changes that would 
complicate things for non-English locales.  I suspect this is not an 
issue for this simple application.)
* htmlview: Use the above defined Preferred Applications in the "right" way.
* htmlview: Avoids known infinite loops.
* htmlview: Prevents invalid browser configurations, forcing user to 
choose a different browser.

These backported improvements also will simplify transition to FC2 later 
for user desktop profiles, as all behavior should behave identically.

I am warning the lists a week in advance so that people may suggest 
other "known good" small fixes for these three packages.  For example 
someone suggested a minor x86_64 crash fix for control-center.  Please 
suggest other fixes.
