I do not know how to reproduce it.

I can easily reproduce this error when trying to go to the definition of some snippets.

I get the same error when I try to rename a file which is in the preview state; Open the file in preview mode, then select "Rename" from the context menu in the explorer view.

I can confirm that @lmcbout's instructions still produce an error in the console, and the widget whose underlying file has been renamed disappears from the shell, even if close-on-delete is set to false.
