Please describe the problem.

I'm getting fatal: unable to normalize object directory while issuing git annex copy from an annex in my laptop to a vanilla remote annex located in a USB disk. As far as I can tell there are no hardware problems with the disk or the laptop.

``` $ git annex copy --auto --to usbdrive . copy vlc-record-2016-07-17-15h16m55s-hr-fernsehen-Die fantastische Reise der Vögel (3_6).ts (to usbdrive...)

But note that the command did not abort. After copying, fsck reports no error:

$ git annex fsck --from=usbdrive 'vlc-record-2016-07-17-15h16m55s-hr-fernsehen-Die fantastische Reise der Vögel (3_6).ts' fsck vlc-record-2016-07-17-15h16m55s-hr-fernsehen-Die fantastische Reise der Vögel (3_6).ts (checksum...) ok (recording state in git...)

I get the same errors with drop, which fails:

``` $ git annex drop --from usbdrive 'vlc-record-2016-07-17-15h16m55s-hr-fernsehen-Die fantastische Reise der Vögel (3_6).ts' drop usbdrive vlc-record-2016-07-17-15h16m55s-hr-fernsehen-Die fantastische Reise der Vögel (3_6).ts fatal: unable to normalize object directory: /home/jr/Videos/ts/../../../../../run/media/jr/TOSHIBA/jr/Videos.git/objects fatal: unable to normalize object directory: /home/jr/Videos/ts/../../../../../run/media/jr/TOSHIBA/jr/Videos.git/objects fatal: unable to normalize object directory: /home/jr/Videos/ts/../../../../../run/media/jr/TOSHIBA/jr/Videos.git/objects fatal: unable to normalize object directory: /home/jr/Videos/ts/../../../../../run/media/jr/TOSHIBA/jr/Videos.git/objects fatal: unable to normalize object directory: /home/jr/Videos/ts/../../../../../run/media/jr/TOSHIBA/jr/Videos.git/objects fatal: unable to normalize object directory: /home/jr/Videos/ts/../../../../../run/media/jr/TOSHIBA/jr/Videos.git/objects fatal: unable to normalize object directory: /home/jr/Videos/ts/../../../../../run/media/jr/TOSHIBA/jr/Videos.git/objects fatal: unable to normalize object directory: /home/jr/Videos/ts/../../../../../run/media/jr/TOSHIBA/jr/Videos.git/objects fatal: unable to normalize object directory: /home/jr/Videos/ts/../../../../../run/media/jr/TOSHIBA/jr/Videos.git/objects fatal: unable to normalize object directory: /home/jr/Videos/ts/../../../../../run/media/jr/TOSHIBA/jr/Videos.git/objects fatal: unable to normalize object directory: /home/jr/Videos/ts/../../../../../run/media/jr/TOSHIBA/jr/Videos.git/objects

But the same drop works if executed again:

$ git annex drop --from usbdrive 'vlc-record-2016-07-17-15h16m55s-hr-fernsehen-Die fantastische Reise der Vögel (3_6).ts' drop usbdrive vlc-record-2016-07-17-15h16m55s-hr-fernsehen-Die fantastische Reise der Vögel (3_6).ts ok (recording state in git...)

What version of git-annex are you using? On what operating system?

git-annex version: 6.20161231-gc8eeb17da

Linux XXX 4.8.13-1-ARCH #1 SMP PREEMPT Fri Dec 9 07:24:34 CET 2016 x86_64 GNU/Linux

Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

Yes! I use git-annex without a problem since years. This is the first time I have really no idea what's going on.

Seems to be fixed in git version 2.19.0 done --Joey
