config.json issue

[lucidbee]

I am bringing up a riemann monitoring system. I kept losing all the non-default customization
for riemann-dash (the definition of the graphs). Eventually I realized what was happening:

If a config.json file exists in the config directory (which in my install is at /var/lib/gems/1.9.1/gems/riemann-dash-0.2.9/config)
then when I do 's' in riemann-dash to save the config.json file, the config.json file is overwritten by config.json for the default startup display, which is an empty view with the title RIEMANN and the help menu.
If there is NO config.json in this directory, then the config.json that is written defines the graphs as I've customized them in reimann-dash.

The user-group for the config.json file is riemann-riemann.
