Yes, this sound like it is the same. We even had similar issues with broken
repositories after failed records. Fortunately, only local development
branches were affected which we could simply throw away w/o loosing
important work.

Fixing this would be /very/ much appreciated. I agree with Zooko (in his
initial report on the related/identical issue815): this is the first
serious problem I have encountered with darcs-2 (on old-style repos) so
far.
