I could reproduce the bug:

1. Take two non-AIFF files, and give them an "aiff" extension and a similar name.
2. Run a filename scan that will make the two files match. (there is no crash yet)
3. Close dupeGuru ME and re-open it. The crash happens when it tries to load the results.

(from [84d4db11b875]) [#123 state:fixed] Updated codebase to use hsaudiotag v1.1.0 (which fixed the AIFF bug) and made it use the new auto.File wrapper.
