### Please describe the problem.
Copying to a gpg encrypted webdav remote (with davfs) seems to work, but fails.
The command "git annex copy --to 1und1 some/file" returns ok, but a fsck fails and running
the copy again copies the file again to the remote.
### What steps will reproduce the problem?
[[!format sh """
git annex copy --to 1und1 some/file # seems ok
git annex copy --to 1und1 some/file # copies again
git annex fsck --from 1und1 some/file # fails
"""]]
### What version of git-annex are you using? On what operating system?
4.20131002 on debian (mostly stable), armel.
### Please provide any additional information below.
I used strace to see what is going on. It seems the chunkcount file is not written. When I create that file by hand fsck is happy.
(git annex seems to have two different locations for that file (dcf/85a and 3W/Qm). The second (3W/Qm) doesn't exist.)
[[!format sh """
# If you can, paste a complete transcript of the problem occurring here.

copy to webdav (git annex copy --to 1und1 some/file)

Quick question: Is there any way to get rid of the error in the existing repository (e.g. remove the problematic tmp file entry) so I can get a complete status output? Bonus points if I don't have to annex every single file anew. `git annex fsck` doesn't work, as doesn't `git annex fix` (it's a direct repo).
