- Electron version:
  1.3.3
- Operating system:
  OSX El Capitan 10.11.6

The following code crashes Electron. The dev tools don't open, but the HTML element highlights like it is open.

``` javascript
selfBrowserWindow.webContents.openDevTools({mode: 'detach'})
selfBrowserWindow.inspectElement(rightClickPosition.x, rightClickPosition.y)
```

The reason I'm doing this is because I want to open the dev tools detached, then inspect. Calling inspectElement first will open the dev tools docked by default.
