I'm sorry you're finding so many problems with the new release.  It's
obvious we've let our codebase degrade badly from sloppy practices.
Hopefully with the testing we're now adding in, this will be much less
common soon.

In the meantime, it seems this is coming from the 'jobctrl' extension.
 Do you use that regularly?  If not, please disable it, as it is the
source of the problem:

In [1]: ls *.zip
wrapping.zip

In [2]: import jobctrl

In [3]: ls *.zip
---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)

ETC...

Just check where in your user config you're importing jobctrl and
comment out the import, until this is fixed upstream.

It's been now filed on the tracker:

Thanks!
