Xapian discuss - Jan 2011 - chert-update creates a db with some errors

I've some problems converting a xapian db, created with core 1.1.3 (using
chert), to the new chert format.
I'm using xapian-chert-update, compiled from the core-1.2.4.

The conversion seems to run without errors:
#./xapian-core-1.2.4/bin/xapian-chert-update old new
postlist: Reduced by 33.3333% 16K (48K -> 32K)
record: Size unchanged (8K)
termlist: doesn't exist
position: Size unchanged (0K)
spelling: Size unchanged (0K)
synonym: Size unchanged (0K)

But if I run xapian-check on the new database there're many errors reported:
#./xapian-core-1.2.4/bin/xapian-check new
postlist:
baseB blocksize=8K items=67 lastblock=3 revision=1 levels=1 root=2
B-tree checked okay
.......
document id 744 in value chunk is larger than get_last_docid() 490
document id 745 in value chunk is larger than get_last_docid() 490
document id 746 in value chunk is larger than get_last_docid() 490
postlist table errors found: 255


I've re-created the 1.1.3 database WITHOUT the values that I add to
documents during the indexing (with the document.add_value)
and in this case the conversion creates a database without errors.

Can someone help me?

It looks like it isn't translating the keys for the value chunks
properly.  Shouldn't be hard to fix.  Do you have a small 1.1.3 database
with values in handy, to save me having to build 1.1.3 myself?
