Subject: [evolution] Remove some obsolete GConf keys.
Date: Sat, 19 Dec 2009 05:49:40 +0000 (UTC)
commit 60e6ecbb42bf19c23638cd4b7643b2ec19320b57
Author: Matthew Barnes <mbarnes redhat com>
Date:   Sat Dec 19 00:46:19 2009 -0500

    Remove some obsolete GConf keys.
    
    /apps/evolution/mail/display/show_preview
    /apps/evolution/mail/display/thread_list
    
    These keys are no longer needed since we're storing the settings by
    folder now in ~/.evolution/mail/config/state.  To simplify things we use
    hard-coded defaults: TRUE for PreviewVisible, FALSE for GroupByThreads.
