Probably the damage was done to the database before the bug was fixed.

You could try using copydatabase (in xapian-examples) to recreate the
database from itself.  Because of how it works, it regenerates the
postlists from the termlists, so it should fix this (and indeed any
postlist corruption problems).  It'll take a while to run for a large
database, but should be quicker than indexing from scratch.
