Mac ipfs daemon --mount and OSXFUSE

Hi

I'm having problems mounting /ipfs - I've installed ipfs and OSXFUSE (2.8.0, via a .dmg package), but get the following error.

Jamess-MacBook:~ jamescarlyle$ ipfs version
ipfs version 0.3.8-dev

Jamess-MacBook:~ jamescarlyle$ ipfs daemon --mount
Initializing daemon...
Swarm listening on /ip4/127.0.0.1/tcp/4001
Swarm listening on /ip4/172.16.51.60/tcp/4001
API server listening on /ip4/127.0.0.1/tcp/5001
Gateway (readonly) server listening on /ip4/127.0.0.1/tcp/8081
Error: config key invalid: DontCheckOSXFUSE %!s(bool=true)
You may be able to get this error to go away by setting it again:

```
ipfs config DontCheckOSXFUSE true
```

The current .ipfs/config file has the following line
"DontCheckOSXFUSE": true,
This looks valid to me - i.e. the Error looks invalid.

Happy to try anything else, reinstall etc., keen to hear if anyone else can repeat this error.
