CentOS - Sep 2006 - yum: could not load sqlite, falling back to pickle

After cleaning up the issues with yum consuming the machine by 
allocating memory until it croaked (versioning issue with sqlite), 
and with the machine now stable and fully updated, I happened to 
notice this message at the start of yum runs:

   # yum check-update
   Warning, could not load sqlite, falling back to pickle

Is this expected, or indication of a further problem?
