[Tutor] subprocess not returning

[shawn wilson]

This works when I have a class for ldd and nothing else, but when I
run it like this:
https://gist.github.com/ag4ve/11171201

I don't get any of the libraries and I can't figure out where it's failing.
['fattr', [['/testroot', 0, 0, 777], ['/bin/dash']]]
HERE1 [/testroot]
HERE2 [/bin/dash]
['ldd', ['/lib/x86_64-linux-gnu/libc.so.6', '/lib64/ld-linux-x86-64.so.2']]
HERE2 [/lib/x86_64-linux-gnu/libc.so.6]
['ldd', ['/lib64/ld-linux-x86-64.so.2']]
HERE2 [/lib64/ld-linux-x86-64.so.2]
['ldd', ['statically']]
HERE1 [statically]
HERE2 [/lib64/ld-linux-x86-64.so.2]
['ldd', ['statically']]
HERE1 [statically]
[   'filelist',
    [['/testroot', 0, 0, 777], ['/bin/dash', 0, 0, '755'], [[[]], []]]]

Obviously it's returning something - but no usable info.
