I had the same problem when upgrading from Q to R but I also had the same crash from a running local django 'runserver' instance, so the root cause for this may not be in python-novaclient.

I'm getting this just trying to feed a requirements.txt file into pip inside a virtualenv.

Recreated the virtualenv and it works again, so it must have been something in the virtualenv.

and after that this works again.

I don't see yet why the import fails, because the extensions didn't change, and _sre is built as a builtin anyway.

So maybe libpython2.7-minimal should break python2.7-minimal (<< earlier version)?

This bug was fixed in the package python2.7 - 2.7.4-1ubuntu1

---------------
python2.7 (2.7.4-1ubuntu1) raring; urgency=low

* Merge with Debian; remaining changes:
- Build-depend on python:any instead of python.

python2.7 (2.7.4-1) experimental; urgency=low

  * Python 2.7.4 release.
    - Issue #17550: Fix the --enable-profiling configure switch.
    - Issue #15801 (again): With string % formatting, relax the type check
      for a mapping such that any type with a __getitem__ can be used on the
      right hand side.
    - Issue #17625: In IDLE, close the replace dialog after it is used.
    - Issue #17531: Fix tests that thought group and user ids were always
      the int type. Also, always allow -1 as a valid group and user id.
    - Issue 17538: Document XML vulnerabilties
  * Byte-compile files in libpython2.7-dbg.
  * libpython2.7-minimal: Break earlier python2.7-minimal versions.
    Closes: #704084. LP: #1157687.
  * Call python with -E -S for the byte compilation.

here's a workaround:
http://stackoverflow.com/a/16299628

If you are using virtualenvwrapper then you can recreate the virtualenv on top of the existing one (with no environment currently active):

mkvirtualenv <existing name>

which should pull in the latest (upgraded) python version from the system and fix any mismatch errors.
