+One way to reproduce this is to replace the git repository with a copy
+produced with eg `cp -r` (not `-a`), with the file unlocked before that
+point. Eg:
+
+ #!/bin/sh
+ set -e
+ cd tmp
+ sudo rm -rf xx yy xx.old
+ git init xx
+ cd xx
+ git annex init
+ echo hi > foo
+ git annex add foo
+ git annex unlock foo
+ git commit -m add
+ cd ..
+ git clone xx yy
+ mv xx xx.old
+ sleep 10
+ cp -r xx.old xx
+ cd yy
+ git annex init
+ git annex get foo
+
+I doubt this is what people have been doing to see the behavior though.
