gitlab-rake assets:precompile fails with permission denied error

I've just installed GitLab from the latest omnibus package (7.12.2) and was trying out some of the gitlab-rake tasks. I tried to run gitlab-rake assets:precompile but it seems to be failing with a permission error.

The error seen when running the gitlab-rake task is:

root@gitlab-precise:/home/test# gitlab-rake assets:precompile
rake aborted!

See:

The bottom line is that you should never need to run gitlab-rake assets:precompile for an omnibus installation, only for source installations.
