Package: python-pkg-resources
Version: 18.7.1-1
Severity: grave
Control: affects -1 git-buildpackage whatmaps
Justification: renders package unusable

Since the recent upgrade of packages built from the python2.7 source
package, multiple unrelated programs bail out with the following
backtraces, at least "gbp pull" and "whatmaps".

It always boils down to this line of code and backtrace:

→ python

Even only sourcing
/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py causes that
backtrace:

UnicodeDecodeError: 'utf8' codec can't decode byte 0xb6 in position 147:

Downgrading python-pkg-resources and python-setuptools to 18.7-1
solves the issue.
