Fuse mount panic runtime error

Ran the following command:

$ sudo ./weed mount -filer=localhost:8888 -dir=/seaweedfs -volumeServerAccess=filerProxy -filer.path=/
This is SeaweedFS version 30GB 2.31 f5b5e4d linux amd64

Got this error after removing a file:

Is it always reproducible?

[johncadengo]

@chrislusf thanks for fixing.

Here is how I was reproducing it. Have a terminal window open and run this, while in the mounted directory,

$ watch -n 1 ls -a .

And in another window erase a file,

$ rm filename

thanks! seems working fine with the latest code.
