commit 94d47dc25e91ddcd9fd9d87995bd2355f93499fe

    Make sure all workspaces have a non-empty, non-null name
    
    The change to using gconf_client_all_entries() in commit 2d57b1b4
    meant that workspaces without a GConf key for their name were not
    getting a name at all. Fix this by doing a post-processing loop
    to set workspace names that were not otherwise set.
    
    Alternate to patch from Tomas Frydrych
