OK, I'm happy to test for you :)

Hmm, no I don't believe I have it all backed up. Nor do I have a spare
20GB to make a copy of the Karma...

It did it automagically when I powered up after the paperclip reset.

I tend to agree with you there.
I applied the attached lk_karmaUsb_write_smalldb_perror.patch along with
the two patches you posted in the other mail. It's now much better, see
attached karma_debug_take2.log; but riocp still seems to be messing with
smalldb in uncertain ways. See especially the file sizes before/after
each query.

Yes, with a few patches that have been posted here and in the hg repo.
See http://people.debian.org/~jello/libkarma_0.0.6-1.diff.gz for all the
details.

I'm jello on irc.debian.org (OFTC) or irc.freenode.net. Just /msg jello
and I should reply.
Thanks again for all your efforts and hard work!
