 @
davidfor - re the problem reported by mariekes and bmcs. I am seeing this in the select library drop down:
I would expect to see 
something like this list from 
gui.json
	Code:
	  "library_usage_stats": {
    "D:/Calibre/Libraries/Books": 213, 
    "D:/Calibre/Libraries/Default": 8, 
    "D:/Calibre/Libraries/Empty": 5, 
    "D:/Calibre/Libraries/Intake": 73, 
    "D:/Calibre/Libraries/Journals": 305, 
    "D:/Calibre/Libraries/Media": 1042, 
    "D:/Calibre/Libraries/Test": 921
  },
 But it appears I'm seeing this list from 
history.plist
	Code:
		<key>lineedit_history_find_duplicates_plugin:library_duplicate_combo</key>
	<array>
		<string>D:\Calibre\Libraries\Books</string>
		<string>D:\Calibre\Libraries\Intake</string>
		<string>E:\Calibre Libraries\Test</string>
		<string>D:/Calibre Libraries/_Empty</string>
		<string>D:/Calibre Libraries/_Media</string>
		<string>D:/Calibre Libraries/_Main</string>
		<string>E:\Calibre Libraries\Main</string>
	</array>
 Perhaps you could look into why this is happening?  Maybe something changed in a recent release.  I stopped using Find Duplicates->Library Duplicates feature when DaltonST released CalibreSpy.
After closing calibre, I was able to remove the 
lineedit_history_find_duplicates_plugin:library_du  plicate_combo block, and then use the browse button to locate one of my existing libraries with no side effects.  That of course recreated the list in 
history.plist.  I'm hesitant to suggest mariekes and bmcs do similar before you respond.
