Partial and full repositories use the same format.  The only
difference is that some patches are missing in a partial repository.

So when Darcs fails to read a patch file which it expected to find,
there's no saying why -- it may be because the repository is partial,
or it could be because of some other problem.

(In other words: in order to create a partial repository by hand, just
make a checkpoint and delete random files under _darcs/patches; but
don't try that at home, kids!)

It looks like either your repository is corrupt, or a bug in Darcs.
What does check say?
