Package: python3-xapian-haystack
Version: 2.1.0-2
Severity: serious
User: helmutg at debian.org
Usertags: python-import

After installing python3-xapian-haystack importing the module xapian_backend
into a python interpreter fails with the following error:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/xapian_backend.py", line 10, in <module>
    from django.utils import six
ModuleNotFoundError: No module named 'django'

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.
