Mavericks Unhandled 'error' event.

Nobody has claimed this yet.

When trying to upload an image to s3 on Mavericks I'm seeing

```
00:23:45 web.1 | events.js:72
00:23:45 web.1 | throw er; // Unhandled 'error' event
00:23:45 web.1 | ^
00:23:45 web.1 | Error: read ECONNRESET
00:23:45 web.1 | at errnoException (net.js:901:11)
00:23:45 web.1 | at TCP.onread (net.js:556:19)
00:23:45 web.1 | exited with code 8
00:23:45 system | sending SIGTERM to all processes
```

I've read the other issues on here with similar errors and the solutions seem to be to either ensure that ImageMagick is installed or to set the region for your S3 configuration.

I've tried both.

Any advice here? Im completely lost. Ive reinstalled ImageMagick with homebrew and my config file includes the region:

```
region: 'us-standard'
```

The payload names no source file or test. Start by reproducing the S3 image upload on Mavericks, then inspect the S3 configuration, including region: 'us-standard', and the ImageMagick setup; done means the upload completes without the reported ECONNRESET and unhandled error.
