- Electron version: 0.36.9
- Operating system: Mac OSX 10.11.14

When I click on a link that triggers a file download, it emits a `did-fail-load` event with an error code `-3`. The download works and is saved as expected though. 

As a side note, I was calling `loadURL` in the `did-fail-load` handler which caused Electron to crash. I can provide the full dump for that if you'd like. 

Let me know if you'd like any more details.
