Is the message preceded by something like "lossy conversion of
If so, then although the final state of the repository is the same as in
the pre-conversion repository, some aspects of the history have been
lost. In particular if you had patches A, B, C in that order (perhaps
separated by some other patches), where A and B conflicted and C
resolved the conflict, then the converted repository will effectively
lose the contents of B, replacing it with a patch that undoes the effect
of A instead. After C things will be back to normal.
Really the conversion should be cleverer than this and produce a darcs2
format conflict instead, but I think this was inadvertently disabled -
see http://bugs.darcs.net/issue1809 for a bit more explanation.
