corrupt bbdb database, & what to do abouti t?

[Matt Price]

after two events in rapid succession -- a hard hang on emacs that
required me to kill the process, and a minor upgrade of my system
(running snapshot packages on ubuntu lucid), my bbdb database appears
to be corrupt.  i'm just wondering what i ought to do about that, as i
spent quite a while harvesting these addresses & don't want to lose
them entirely.  here's my error message:

----------

has anyone ever seen this before?  i'm guessing my bbdb db is corrupt
but i'd rather not build it back from scratch, so if anyone has any
advice it'd be really helpful.  thanks much,
matt
