+Reproduction script:
+
+	chmod -R +w bench 2>/dev/null
+	rm -rf bench 2>/dev/null
+	mkdir bench
+	cd bench
+	git init a
+	cd a
+	git-annex init
+	touch foo
+	git-annex add foo
+	git commit -m add
+	cd ..
+	git clone a b
+	cd b
+	git-annex get
+	git-annex drop
+	git-annex get
+	git-annex drop
+	cd ../a
+	git-annex sync
+	git-annex forget --force
+	git-annex sync
+	git-annex log foo
+	cd ../b
+	git-annex sync
