I have a repository that is ill-formed, and when I touch one of the broken
files darcs errors out, and I can't fix it by "darcs repair".  I think that the
problem is that the addfile change has gone missing for a file.  See:

Is there any workaround that I can use to make this repository fully
operational again?  Perhaps a new version of darcs (I would be more than happy
to test a patch) which detects and repairs this kind of situation?

Regards,

Zooko

We eventually found another patch by the same name in another repository which
added the right file, and so we could work around this problem by overwriting
the bogus patch with that other one.

However, we now encounter similar problems with other patches that we don't know
how to work-around.

Okay, we found a repository which wasn't broken and switched over to using that.
 So now we're no longer stuck on this bug.

Without clearer example of how the repository became "broken", I don't think
we'll be able to do much with this bug report.

Since I can't tell how the repository got this way, and since we hope that
darcs-2 does things sufficiently differently that it will have different bugs,
let's close this one.
