In the last release (0.5.9) when I do a fuse preview via Terminal I get this error:

Hi Cristian, good to hear that it works again! It’s hard to know exactly what happened in this case without more information, but if it happens again, could you please try to exit Fuse via the tray menu? That should be less severe, but hopefully just as effective.
