Based on information from user who originally reported this ticket, I have debugged this issue. It seems the problem is editor.focus(); in onHide method in find.js file.

When debuging code manually error is not thrown so a good workaround for this issue is warping editor.focus() in

CKEDITOR.tools.setTimeout( function() {
  editor.focus();
}, 0, this );

Still after calling editor.getSelection().selectRanges( [ range ] ); start/end offsets show 0/1 (not 03). In order to fix offsets you need to call editor.getSelection().getRanges()[0].moveToRange(range); but you should rather not be doing that in a first place so this is another workaround just for offsets.
