Bug#896226: python-v-sim: gi.overrides.v_sim fails to import

[Helmut Grohne]

Package: python-v-sim
Version: 3.7.2-5
Severity: serious
User: helmutg at debian.org
Usertags: python-import

After installing python-v-sim importing the module gi.overrides.v_sim
into a python interpreter fails with the following error:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/gi/overrides/v_sim.py", line 48, in <module>
    v_sim = modules['v_sim']
KeyError: 'v_sim'

The vast majority of import failures is attributed to missing dependencies.
Often times that manifests as an ImportError or ModuleNotFoundError.
Typically, dependencies should be inserted by dh-python via ${python:Depends}
or ${python3:Depends}. Thus a missing dependency can be caused by incomplete
install_requires in setup.py. Sometimes a missing dependency of a dependency
is the cause, in such cases this bug should be reassigned.
