After looking at the code, the most plausible explanation seems to be
that the index on pg_largeobject is broken.  Try reindexing
pg_largeobject.  (You'l likely need to do this in single-user mode;
read the REINDEX man page carefully.)

7.2.1 is by no means current, btw.  I recommend an update to 7.2.4 at
least, or 7.3 if you can.
