Steps to reproduce:
1) Open a .CSV file in Pulseview.
2) Without closing the .CSV, close Pulseview.
3) Delete or modify the CSV file.
4) Re-open Pulseview.
Pulseview re-scans the file or shows a warning that it has changed.
Pulseview usually crashes. It *always* crashes if the file was deleted and it *sometimes* crashes if the file was modified.
