    Bug 661542 - Weird "Cannot upgrade from version 0.xxxx" on first use
    
    GConf's default value for the version key is an empty string, which
    causes "sscanf (string, "%d.%d.%d", major, minor, micro)" to fail and
    leaves the major/minor/micro variables uninitialized.
    
    Instead, initialize the up front before reading the GConf key.
