+### Please describe the problem.
+
+When git annex is used on a encfs mount, .fuse_hiddenXXXX files are left behind in .git/annex/objects/*/*/ when I ``git annex move`` files off the encfs
+
+### What steps will reproduce the problem?
+
+ mkdir normal plain enc
+ encfs -o kernel_cache "$(realpath enc)" "$(realpath plain)"
+
+ cd normal
+ git init
+ git annex init normal
+
+ cd ../plain
+ git init
+ git annex init enc
+ dd if=/dev/urandom bs=1M count=11 of=11m
+ git annex add 11m
+ git remote add normal "$(realpath ../normal)"
+ du -hscL *
+ << 11MB-ish >>
+ du -hsc .git/annex/objects
+ << 11MB-ish >>
+ git annex move --to=normal 11m
+ du -hscL *
+ << 0 >>
+ du -hsc .git/annex/objects
+ << 11MB-ish but should be 0-ish >>
+ tree -a .git/annex/objects
+ << ??/??/SHA1-*/.fuse_hidden??????? >>
+ lsof .git/annex/objects/??/??/SHA*/.fuse_hidden*
+ << shows no programs have this file open >>
+
+
+### What version of git-annex are you using? On what operating system?
+
+5.20131221 on debian unstable (installed by aptitude from debian/main)
+
+### Please provide any additional information below.
+
+I did a couple quick internet searches on these .fuse_hidden files, and (if a random person on the internet is correct) they are created by enfs (or maybe fuse itself) when a file is unlinked while open. It is supposed to be deleted when the file is closed.
+
+Possibilities come to mind:
+
+* There's a bug in encfs/fuse
+* git annex fails to close the file, and whatever cleanup happens when the linux kernel closes git annex fails to trigger encfs/fuse's real unlinking/cleanup thing
+
+
+
+I'm happy to help with further testing, experimenting, etc. I'm good at git, the commandline, programming, etc but I don't know Haskell.
