Strange error with multiple tracebacks

[nuklea]

I'm trying to clone python2 virtual env.

$ /usr/bin/python2 -m clonevirtualenv -v ~/.virtualenvs/project ~/.virtualenvs/project-django15
cloning virtualenv '/home/nuklea/.virtualenvs/project' => '/home/nuklea/.virtualenvs/project-django15'...

It has started to do some stuff, it created the dir:

$ ls /data/jenkins/.virtualenvs/duplicated-master
bin  include  lib  local  man  pip-selfcheck.json  share  src
$ ls /data/jenkins/.virtualenvs/duplicated-master/lib/python2.7/site-packages/
...all the packages appear to have been copied ok...
...but...
$ pip freeze

more info, the script has done something weird to the path in the original virtualenv

if I edit /data/jenkins/.virtualenvs/master-branch/lib/python2.7/genericpath.py in my original virtualenv and add a debugging print like:

def exists(path):
    """Test whether a path exists.  Returns False for broken symbolic links"""
    try:
        os.stat(path)
    except os.error:
        return False
+    except TypeError as e:
+       print path
+        raise
    return True

then I see this:

$ /data/jenkins/.virtualenvs/master-branch/bin/python
/data/jenkins/.virtualenvs/duplicated-master/src/txstatsd/data/jenkins/.virtualenvs/duplicated-master/src/pyelasticsearch/data/jenkins/.virtualenvs/duplicated-master/src/django-dirtyfields/src/data/jenkins/.virtualenvs/duplicated-master/src/django-oauth2-provider/data/jenkins/.virtualenvs/duplicated-master/src/neomodelimport sys; new=sys.path[sys.__plen:]; del sys.path[sys.__plen:]; p=getattr(sys,'__egginsert',0); sys.path[p:p]=new; sys.__egginsert = p+len(new)

  File "/data/jenkins/.virtualenvs/master-branch/lib/python2.7/genericpath.py", line 26, in exists
    os.stat(path)
TypeError: must be encoded string without NULL bytes, not str

note the messed up path printed at the top, referencing the duplicated virtualenv, though I have no virtualenv activated and I am trying to run python from my original virtualenv

[anentropic]

the packages from my pip requirements installed as editable seem like they may be implicated somehow

e.g. /data/jenkins/.virtualenvs/duplicated-master/src/txstatsd in the bad path above corresponds to

-e git+git://github.com/myorg/txstatsd.git@50c77b8df8e1dc5ffaf1ba853691d3da280c1b39#egg=txstatsd

in my requirements.txt file

same for all the other parts in the bad path
(before it starts spitting out actual python code import sys; ...)
