+### Please describe the problem.
+After initializing an empty new v7 repo in a remote NTFS drive from linux mounted via CIFS, adding new file fails with a SQLite3 error.
+Using a v5 repo in direct mode works (with git annex init --version=5).

+### What steps will reproduce the problem?

+### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
+
+When initializing the repo with v5 git-annex (git annex init --version=5 test), then the legacy direct mode is used and file addition works well.
