Linux Docker Version 1.11.2 : Bug : Option --workdir breaks "docker run" inside Ubuntu/Trusty running in VirtualBox on Windows 8.1

[ifrh]

Summary:
Inside a Ubuntu/Trusty VM (running in VirtualBox on Windows) the Docker run command with Option "--workdir" failes with Message "docker: Error response from daemon: Container command 'env' not found or does not exist.." - even no other "Container command" got found ...

Output of lsb_release -da:

lsb_release -da 
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04.4 LTS
Release:        14.04
Codename:       trusty

Steps to reproduce the issue:

1. Install Ubuntu/Trusty (64bit) inside Virtualbox (Oracle VirtualBox 4.3.28 r100309) on Windows 8.1 (64bit)
2. Install docker-engine inside Trusty (following docs: https://docs.docker.com/engine/installation/linux/ubuntulinux/ )
3. Create the Docker image using dockerfile from https://github.com/KITPraktomatTeam/Praktomat/blob/master/docker-image/Dockerfile after commenting out their lines for Isabelle2016 support (line 62 to line 65)
   using the command sudo docker build --build-arg=https_proxy="http://www-cache.inf.h-brs.de:8080" --build-arg=http_proxy="http://www-cache.inf.h-brs.de:8080" --no-cache -t safe-docker docker-image
4. Interact with the Docker via script from https://github.com/nomeata/safe-docker or calling docker run [...many Options ...] direct from linux bash like this:

docker run --rm --read-only --sig-proxy --tmpfs /tmp --tmpfs /run --tmpfs /home --net=none --memory=1G --user=1000:1000 --volume=/home/praktomat/inst4git/h_brs_p/Praktomat/src/checker/scripts:/home/praktomat/inst4git/h_brs_p/Praktomat/src/checker/scripts:ro --volume=/home/praktomat/inst4git/h_brs_p/debug-work/SolutionSandbox/tmpzF5jVE:/home/praktomat/inst4git/h_brs_p/debug-work/SolutionSandbox/tmpzF5jVE --workdir=/home/praktomat/inst4git/h_brs_p/debug-work/SolutionSandbox/tmpzF5jVE --name secure-tmp-b9f0f6ab-8d74-46bf-a814-e52feb6c8a34 safe-docker env

The result I received:
From abov docker run command I received this Error message:
docker: Error response from daemon: Container command 'env' not found or does not exist..

The results I expected:
I expected the same result from abov docker run command, if I omit the option --workdir like here

docker run --rm --read-only --sig-proxy --tmpfs /tmp --tmpfs /run --tmpfs /home --net=none --memory=1G --user=1000:1000 --volume=/home/praktomat/inst4git/h_brs_p/Praktomat/src/checker/scripts:/home/praktomat/inst4git/h_brs_p/Praktomat/src/checker/scripts:ro --volume=/home/praktomat/inst4git/h_brs_p/debug-work/SolutionSandbox/tmpzF5jVE:/home/praktomat/inst4git/h_brs_p/debug-work/SolutionSandbox/tmpzF5jVE  --name secure-tmp-b9f0f6ab-8d74-46bf-a814-e52feb6c8a34 safe-docker env

From that I received:

PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
HOSTNAME=79b1ac67f8e0
HOME=/

Additional information you deem important (e.g. issue happens only occasionally):

• The issue happens for me every time.
• Down grading docker-engine doesn't help.
• I also wrote an own static compiled c program, which should print getenv(...)-Values,
  putting it into the workdir but docker run ... cannot find this program:
  docker: Error response from daemon: Container command 'mypath' not found or does not exist..
• I don't know if --workdir also breaks docker run if it doesn't point to a per --volume mounted path.
• I don't know if --workdir also breaks docker run if docker is running in a not virtualised Trusy

Best regards,
Robert
