Sort feature not functional, also breaking symlink feature

[thennicke]

Bug Description

Steps to reproduce:

Open the program, run the duplicate files search on a folder, then attempt to use the sort button to change the sorting arrangement of the items. Expect to see a re-sorted list of files. Does nothing instead. No terminal output at all from this action.

This breaks the symlink feature because it is impossible to change the order of the items, so as to be able to control which is the source and which the destination for the symlink.

Update: The previous report was made without any reference folders being involved. If I add one folder as a reference folder and then compare to another folder, trying to sort now gives me a crash instead, with the following output in terminal:
