In version 5.4.0 I have frequent crashes while applying face tags after a face scan operation. I could not find a pattern, it seems to happen quite randomly. This didn't happen in 5.3.0
Please use current 5.5.0 AppImage bundle instead system version to see if problem is reproducible. https://drive.google.com/drive/folders/0BzeiVr-byqt5Y0tIRWVWelRJenM Gilles Caulier
Seems fixed in last 5.5.0 AppImage
