Sometimes links to annexed data still exists on some branch, when it was supposed to be dropped. Here is how I found these; perhaps there is a simpler way.
% git annex find --format '${key}\n' > /tmp/known-keys
% find .git/annex/objects -type f -exec basename {} \; > /tmp/local-keys
% comm -23 /tmp/local-keys /tmp/known-keys
to look for what branch these are on, try
% git log --stat --all -S$key
for one of the keys output above. In my case it was the same remote branch keeping them all alive.
