319.12 beta - nvidia-settings always overwrites .nvidia-settings-rc

Driver 319.12 beta x86_64.
Every time I run nvidia-settings, the configuration file $HOME/.nvidia-settings-rc gets overwritten and all settings are reset to default values.

For example:

linux-2nwn:0[dpy:1]/RedGamma=0.741000
linux-2nwn:0[dpy:1]/GreenGamma=0.741000
linux-2nwn:0[dpy:1]/BlueGamma=0.741000

becomes

linux-2nwn:0[dpy:1]/RedGamma=1.000000
linux-2nwn:0[dpy:1]/GreenGamma=1.000000
linux-2nwn:0[dpy:1]/BlueGamma=1.000000

In addition, nvidia-settings still creates invalid configuration files; as you can see in the previous example, hostname is present even if the option “Include X Display Names in the Config File” is disabled.
In consequence of this problem, nvidia-settings requires more than a minute to start.

Apparently that is some sort of bug according to:
