fractal tries to measure available space
I found this in the logs right now:
(fractal:11388): Gtk-WARNING **: 11:23:14.663: Failed to measure available space: Error getting filesystem info for /home/me/mnt/remote: Transport endpoint is not connected
The path is a sshfs mount. This message is worrying, because if I had no network connection, and the mount was mounted, the relevant thread would wait for IO, which can take minutes in extreme cases. Some other applications do that, and it's never a nice experience.
Coincidentally, the Fractal instance stopped being able to send messages now.
