package-index error

[Gary Thomas <gary@mlbassoc.com>]

As part of developing a new package for my system,
I've been doing a number of repeated builds like this:
   $ bitbake some-package && bitbake package-index

Over the past two days, I probably ran this command sequence
50 times (lots of iterative development).  On two occasions,
it failed with an error like this:

==============================================================

I've no idea what the error means, nor how I might track it
down.  As mentioned, it's very sporadic and certainly not
stochastically repeatable.  If I immediately rerun the
'bitbake package-index' it works just fine.

Any ideas what this might be?
