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
Python 2.7.11 (default, Dec 9 2015, 00:29:25)
[GCC 5.3.1 20151205] on linux2

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