Please describe the problem.

git annex won't export subdirectories claiming they don't exist. git rev-parse however, returns hashes for said directories which then are accepted by git annex export.

What steps will reproduce the problem?

$ git annex export master:folder --to exp
fatal: Path 'folder:' does not exist in 'master'
git-annex: unknown tree
$ git rev-parse master:folder
943218c141ab2a315b533fa9f92fe610916b5d1b
$ git annex export 943218c141ab2a315b533fa9f92fe610916b5d1b --to exp
export exp testfile2 
ok

What version of git-annex are you using? On what operating system?

git-annex version: 6.20171026-g43d011a52 on Arch Linux
