I just hit this; little bit clearer steps to reproduce:

1. Open Safari and create a window with two tabs
2. Open TextEdit
3. Create new document in TextEdit and save the document.
4. After saving and the proxy icon appearing in the toolbar, drag the proxy
icon and Cmd + Tab to Safari
5. Cmd + W to close one of the tabs
6. BOOM
