Closing last unfocused document tab causes IndexError

[mrclary]

Problem Description

Attempting to close last unfocused document tab in the Editor, after closing next-to-last document, results in IndexError.

What steps reproduce the problem?

1. Open 3 documents, give focus to the left-most document.
2. Close the 2nd document, without giving it focus. This will close properly.
3. Close the 3rd document (which is now in the 2nd tab position). This results in an IndexError.

The issue does not manifest if the document is given focus before closing it, nor does it manifest if one first closes the last document then closes the second document.

What is the expected output? What do you see instead?

Document should close.

Hey @mrclary, thanks for reporting. I've also seen this error while using Spyder.

Could you take care of it?
