python-dap causes "UserWarning: Module dap..." printed in other python programs

[Pauli Virtanen]

Installing python-dap 2.2.6.7-1 causes many Python programs to print messages like

UserWarning: Module dap was already imported from None, but /usr/lib/python2.7/dist-packages is being added to sys.path
  from pkg_resources import load_entry_point

This occurs also when

>>> import pkg_resources
__main__:1: UserWarning: Module dap was already imported from None, but /usr/lib/python2.7/dist-packages is being added to sys.path

These messages are very annoying and pollute program output unnecessarily.

The fix is outlined here: http://stackoverflow.com/questions/13915269/why-do-i-get-userwarning-module-dap-was-already-imported-from-none

Namely, the dap packaging is apparently incorrectly packaged, and missing the top-level module as a namespace package in: /usr/lib/python2.7/dist-packages/dap-2.2.6.7.egg-info/namespace_packages.txt
