+I have a case where `whereis` knows that a file is present in an exporttree
+remote, but `get` fails:
+
+	joey@darkstar:/tmp/bench/repoclone>git annex whereis bar
+	whereis bar (1 copy)
+	  	b1a73a91-5f79-4b4b-b838-683e602b2888 -- joey@darkstar:/tmp/bench/repo
+	
+	  The following untrusted locations may also have copies:
+	  	163219a6-fdc1-4d3e-98a6-7aed3e9d605d -- [dir]
+	ok
+	joey@darkstar:/tmp/bench/repoclone>git annex get bar
+	get bar
+	  Unable to access these remotes: dir
+	
+	  Try making some of these repositories available:
+	  	163219a6-fdc1-4d3e-98a6-7aed3e9d605d -- [dir]
+	   	b1a73a91-5f79-4b4b-b838-683e602b2888 -- joey@darkstar:/tmp/bench/repo
+	failed
+	git-annex: get: 1 failed
+	- exit 1
+
+Reproducible with git-annex 7.20181106-g58d1b2510 using this script.
+
+It looks like the export database is not getting updated to reflect the
+export that was made in the other clone of the repository.
+
