[darcs-users] Couldn't fetch when cloning a repository

[Simon Michael]

Thanks for the ping Ben.

On the server, `darcs check` passes, and I can `darcs get` the repo to a local copy without error. I ran `darcs optimize http` for good measure. But like you, I still can't `darcs get` this repo to a remote machine. I was able to `darcs get` another of Alexis's repos. 

That's a puzzle. Sorry Alexis, I'm going to recommend you try pushing a new copy of this repo under a new name (or delete the old one and re-push to a new repo with the same name) and see if that "fixes" it.
