Description of problem:
On freshly updated F26 I am getting this error:
ImportError: /usr/lib64/python3.6/site-packages/rpm/_rpms.cpython-36m-x86_64-linux-gnu.so: undefined symbol: spec_Type

This is when running pylint-3, but the culprint seems to be in python3-system-libs.

Version-Release number of selected component (if applicable):
$ rpm -qf /usr/lib64/python3.6/imp.py
system-python-libs-3.6.1-6.fc26.x86_64
$ rpm -qf /usr/lib64/python3.6/site-packages/rpm/_rpms.cpython-36m-x86_64-linux-gnu.so
python3-rpm-4.13.0.1-4.fc26.x86_64

How reproducible:
determinist

Steps to Reproduce:
1.pylint-3 /usr/lib/python3.6/site-packages/mockbuild/util.py

Actual results:
************* Module mockbuild.util
R:138, 4: Too many nested blocks (6/5) (too-many-nested-blocks)
C:218,15: Do not use `len(SEQUENCE)` as condition value (len-as-condition)

Note that there are two traceback. And for this report is likely relevant only the first one.
