Files dropping out of index??? (beagle-0.2.16.3)

I'm losing all the files from my index!?

I would expect to have ~100000 files indexed.  But

    hildegard<735>: beagle-index-info
    Index information:
    Name: EvolutionMail
    Count: 41255
    Crawling: False

    Name: Files
    Count: 55
    Crawling: False

    Name: IndexingService
    Count: 123
    Crawling: False

So I tried kicking a file I know should have been indexed

    hildegard<736>: touch /disk/b/mail/Mail/pers-2005-12/572

    hildegard<740>: egrep pers-2005-12/572 ~/.beagle/Log/2007*IndexHelper

    hildegard<743>: egrep pers-2005-12 ~/.beagle/Log/2007*Beagle

So it _was_ indexed originally, disappeared at some point (why!?), but
is capable of being indexed again. . .

So I tried stopping the demon, clearing the whole index away and
restarting the demon.  After about an hour, I saw

    hildegard<748>: beagle-index-info
    Index information:
    Name: EvolutionMail
    Count: 41255
    Crawling: False

    Name: Files
    Count: 40323
    Crawling: True

    Name: IndexingService
    Count: 123
    Crawling: False

Which looks much more like it.

But two days later, we're back to

    hildegard<755>: beagle-index-info
    Index information:
    Name: EvolutionMail
    Count: 41255
    Crawling: False

    Name: Files
    Count: 54
    Crawling: False

    Name: IndexingService
    Count: 123
    Crawling: False

Anyone ever seen anything similar?  Any clues how to fix this?  I
don't believe it used to happen with earlier versions . . .

[There has been a kernel upgrade on my machine recently, now running

   Linux version 2.6.18-1.2257_FC5_dice_1.2smp
   (root berwick inf ed ac uk) (gcc version 4.1.1 20070105 (Red Hat
   4.1.1-51)) #1 SMP Fri Feb 23 13:03:27 GMT 2007

I suppose I could try recompiling from scratch in case there's some
obscure dependency problem. . .]

Thanks in advance,
