Unexpected "No such file or directory" in nextcloud.log

[not-a-user]

Steps to reproduce

1. set 'datadirectory' => '/var/owncloud/data', in config.php
2. upload an mp3 file
3. log out
4. log in

Expected behaviour

Tell us what should happen

No warnings expected in nextcloud.log.

Actual behaviour

Tell us what happens instead

nextcloud.log has

{"reqId":"nHnd9SzFlfbPvZ7xWdri","remoteAddr":"***REMOVED SENSITIVE VALUE***","app":"PHP","message":"fopen(\/var\/owncloud\/data\/***REMOVED SENSITIVE VALUE***\/files\/var\/www\/owncloud\/core\/img\/filetypes\/audio.svg): failed to open stream: No such file or directory at \/var\/www\/owncloud\/lib\/private\/Files\/Storage\/Local.php#216","level":3,"time":"2017-02-22T06:40:08+00:00","method":"GET","url":"\/owncloud\/index.php\/core\/preview.png?file=%2F***REMOVED SENSITIVE VALUE***.mp3&c=f81d88be86da7b4be5c7553d0a73b09c&x=32&y=32&forceIcon=0","user":"***REMOVED SENSITIVE VALUE***","version":"11.0.1.2"}

and similar, all referring to the same path.

I'm afraid the argument to fopen is the concatenation of my data directory and the nextcloud install directory. This looks like a bug.

No similar warnings for other file types.
