Title:
  python2.7-dbg unable to import non-dbg C modules

Status in “python2.7” package in Ubuntu:
  New

Bug description:
  python2.7-dbg will attempt and fail to load non-debug C modules when
  the debug packages are not installed. For instance, I get the
  following exception when trying to import dbus:

  evan at caron:~$ python2.7-dbg
  Python 2.7.2+ (default, Oct  4 2011, 21:24:50) 
  [GCC 4.6.1] on linux2
  Type "help", "copyright", "credits" or "license" for more information.
  >>> import sys
  [39102 refs]
  >>> sys.excepthook = sys.__excepthook__
  [39102 refs]
  >>> import dbus
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    File "/usr/lib/python2.7/dist-packages/dbus/__init__.py", line 79, in <module>
      import dbus.types as types
    File "/usr/lib/python2.7/dist-packages/dbus/types.py", line 6, in <module>
      from _dbus_bindings import ObjectPath, ByteArray, Signature, Byte,\
  ImportError: /usr/lib/python2.7/dist-packages/_dbus_bindings.so: undefined symbol: Py_InitModule4_64
  [40053 refs]

  (I reset the excepthook because apport imports apt_pkg, which also
  triggers this issue and complicates the backtrace)

  Installing the python-dbus-dbg package works around this issue
  successfully, but there's no indication in the docs that this is
  necessary.
