I've just used another fuse based software to mount external drives
(to be precise smestorage binary furnished here http://www.smestorage.com)
After mounting the filesystem, and launching vifm inside the directory I get the following error.
The pattern inverted did not match any files. It was reset.
The only way to get out seems to be to kill vifm (else with ctrl-c, vifm will show the message again and again).
Note that as it was the first time I used this tool the corresponding directory was empty. Moreover I noticed that a ls -a in the corresponding directory does not show . and .. just nothing. I don't know if it could explain the problem. If I had one file in the directory the error message stops.
Not sure it's a real bug. Just to let you know that it could exist such strange directories without anything in it.
