Try your apps in locked-down mode

[Havoc Pennington <hp redhat com>]

Hi,

When writing preferences-related code, you want to test by editing
/etc/gconf/2/path and comment out the readwrite database:

# Give users a default storage location, ~/.gconf
# xml:readwrite:$(HOME)/.gconf

Now gconftool-2 --shutdown so gconfd will restart, and restart your
app. 

When the app is restarted, it should not let you do anything that
results in changing a gconf key. If it does, you should get the
libgnomeui error dialog (I just put in a fix so you'll only get one,
previously you would have gotten spammed with them).

Typically the way you fix these bugs is by calling 
 gtk_widget_set_sensitive (widget_controlling_a_key,
                           gconf_client_key_is_writable (client, key));

If you want to be bad-ass you can redo the sensitivity when you get a
notify, since notifies may indicate that writability changed, but
currently gconf won't reliably change the writable bit at runtime
anyway.
