Usage with systray-rs

[lucasfernog]

When I try to use web-view with the systray-rs library, I get an Aborted (core dumped) error. Do you know if that's something related to GTK not supporting two instances running at the same time?

Sample code:

let app = systray::Application::new()?;
loop {
  match webview.step() {
     Some(Ok(_)) => (),
     Some(e) => e?,
     None => return Ok(()),
  }
}

If I remove the app assignment, the webview works fine. If I leave it (even if i'm not using the systray, just creating a new instance), the app crashes on webview.step(), with the core dump error.
