'cd' is broken (unsure, difficult to reproduce)

[dvalters]

The last merge (#11) seems to break the cd command when trying to cd into the mountpoint, but curiously not when using the GUI file browser in linux?

Steps to reproduce:

1. Mount a netCDF file as in the Readme instructions
2. cd into the mountpoint e.g.:

cd mountpoint

sed: error while loading shared libraries: libacl.so.1: cannot read file data: Error 21

Edit: possibly related: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=747941

Error 21 is given in the Linux Programming Manual (man errno) and http://www.ioplex.com/~miallen/errcmp.html as:

EISDIR          Is a directory (POSIX.1).

Trying to open a file as a directory???

Also sometimes Error 14 (Bad Address):

[dav@W520 trial]$ cd mntpoint/
sed: error while loading shared libraries: libacl.so.1: cannot read file data: Error 14

Well now I can only reproduce this on one computer now so I don't know if this is a true bug...

Above error message(s) on this system:
On Fedora Linux 4.15.15-300.fc27.x86_64
Python version 2.7.14
fusepy 2.0.4

but not reproducible with
Fedora Linux 4.17.3-200.fc28.x86_64
Python version 2.7.15
fusepy 3.0.0 # <--- this also doesn't make sense since the latest version should only be 2.0.4...
