Details:

Patch 08baf0ebc9a9 for bug #47529 appears to have introduced a regression.

If the editor is opened before a file is loaded, it creates a blank window. 
The above patch "reuses" that window for the first file that is opened.

Actions such as paste and undo are all "doubled" for that window, as if it is
getting two copies of the corresponding signal.

A work-around is to close the unnamed window explicitly before opening a file,
or to close the first file opened.

I'm trying to find where the duplicate initialisation is done.  In the worst
case the patch can be backed out.
