Job fails silently when the Docker image+tag doesn't exist

I submitted a job that failed without any standard error or standard output, with no explanation. In order to see what went wrong, I had to go into the developer console and look at the JES log, which pointed out that

2016/02/16 18:16:15 W: "docker --config /tmp/.docker/ pull broadgdac/correlate_genomic_events:35" failed: exit status 1: Pulling repository docker.io/broadgdac/correlate_genomic_events
Tag 35 not found in repository docker.io/broadgdac/correlate_genomic_events

It would be great if there was a better notification that this was the error, which doesn't require investigation of the JES logs.
