OpenScene Twice Causing "PlayerLoop Called Recursively"

I'm currently doing the following, via an Editor script:

1. Open a scene.

2. Play the scene. Wait for an event indicating scene completion.

3. Stop the scene playing.

4. Load another scene.

This works fine, until Step 4. I get an error, PlayerLoop called recursively! Note that this error gets thrown on the EditorApplication.OpenScene line, but it gets thrown whether or not I give it a valid path for a scene. Anyone got any idea why this is happening? Is it because I'm performing OpenScene twice within a single execution? I can't think of a reason why this would happen.

EDIT - Note that this doesn't seem to crash anything. The editor can continue executing code. For instance, both Log statements print out:

 Debug.Log ("Here comes the error!");
 EditorApplication.OpenScene("/path/to/scene.unity");
 Debug.Log ("This is fine, though.");

But obviously it's probably not a good sign.
