I experienced this problem once -- during a pull, and apparently after
Darcs had written out the "the following files had conflicts" bit --
and although it left the *repo* in a sane state, the working directory
was all in pieces.

This is a general problem with Darcs: the working directory operations
are not atomic, so any repo operation that changes the working
directory risks applying changes that are subsequently not associated
with their patches.
