gcloud crashes on gcloud docker pull

[GoogleCodeExporter]

What steps will reproduce the problem?

For me, every time I run the following:
nickyt@es-qa-master-1:/var/log$ sudo gcloud docker pull 
gcr.io/porch-gcp/elasticsearch:0.0.6
ERROR: gcloud crashed (ValueError): No JSON object could be decoded

If you would like to report this issue, please run the following command:
  gcloud feedback

I have tried `gcloud components update` and `gcloud components reinstall` and I 
get the same error every time.  Notably, I can successfully run that command on 
other machines.  I cannot reproduce it on other machines.

What is the expected output? What do you see instead?

I reproduced it on another machine after taking the same steps before running 
into the issue:
1) The machine was out of space
2) /var/log/docker.log taking up 60%, don't care about it
3) echo "" > /var/log/docker.log 
4) Space is free now 
5) restart docker 
6) try to pull `sudo gcloud docker pull gcr.io/porch-gcp/elasticsearch:0.0.6`
7) get error

This is solved by deleting /root/.dockercfg (it was an empty file).

The file is regenerated the next time gcloud is run.

Thanks for the report and solution. The empty /root/.dockercfg was probably due 
to the system out of space. It had enough space to create the file but not 
enough to add its contents. An internal issue is being filed on this.
